If you have a 92.0 gram sample of water, then what mass of hydrogen and what mass of oxygen are in the sample? Make sure you answer in “grams” of Hydrogen and “grams” of Oxygen.



\boxed{\text{10.29 g H and 81.71 g O}}


The formula of water is H₂O.

1. Calculate the molar mass of water

2 H = 2 × 1.008 =   2.016 u

1 O = 1 × 16.00  = 16.00   u

                  MM = 18.02    u

2. Mass of hydrogen

\text{Mass of H} = \text{92.0 g water} \times \dfrac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g\text{Mass of H} = \text{92.0 g water} * \frac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g H} H}

3. Mass of 0xygen

\text{Mass of O} = \text{92.0 g water} * \frac{\text{16.00 g H}}{\text{18.02 g water }} = \textbf{81.71 g O}\n\n\text{The masses are } \boxed{\textbf{10.29 g H and 81.71 g O}}

Final answer:

A 92 gram sample of water will consist of approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.



consists of two hydrogen atoms and one oxygen atom. Therefore, it has a

molecular formula of H2O

. To find the mass of each element in a 92 gram sample, we need to know the molar mass of the elements and the compound. The molar mass of hydrogen (H) is about 1 gram per mole, and oxygen (O) has a molar mass of 16 grams per mole. So, the molar mass of water (H2O) is approximately 18 grams per mole (2*1 + 16). This means that in one mole of water, 2 grams are hydrogen and 16 grams are oxygen. If we scale this up to 92 grams, we find that there are approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.

What mineral is this? Irregularly shaped, white with nonmetallic luster, the hardness of 2.5, shows cubic cleavage and dissolves easily in water.



The material we are talking about would be serpentine.


This material is available in two colours green or white and it has a hardness that amounts to 2.5. This material has a luster that is nonmetallic and more of waxy in nature.  

This feature becomes Satiny when Nature of is material is Fibrous. This material is used as an insulating material against electricity as well as heat. The property of this mineral is very close to asbestos and is used when prevention from heat and electricity is required.




Halite is the mineral  which is called as Rock salt shows cubic cleavage

Halite forms clear transparent crystals with perfect cubic cleavage. Halite is Table salt, the salt is an array of small cubic fragments, the result of halite’s crystal structure and perfect cubic cleavage

Cubic cleavage can be produced by breaking the sample. Halite is one of the few common minerals that, when broken into small fragments, will readily dissolve in water.

How many moles of cobalt (Co) atoms are there in 6.00 times 10 to the 9th power cobalt atoms?



In 6.00 * 10^9 of cobalt atoms there are 6.00 * 10^9 mol Co


Step 1 : Identify the relationship between 1 mole Cobalt  and Avogadro's number of atoms.

1 \text{mole Cobalt }   = 6.022 * 10^(23) \text{ atoms of cobalt }

Avogadro’s number is  number of units present in one mole of any substance (defined as its molecular weight in grams)

Step 2:  Divide the given atoms of cobalt by the number of atoms per mol.

Given atoms of cobalt is  6.00 * 10^9

Now by performing division

Number of moles of cobalt (Co) atoms in  6.00 * 10^9  cobalt atoms is

= (6.00 * 10^9)/(6.022 * 10^(23))

= 0.996 * 10^9 * 10^(-23)

= 0.996 * 10^(9 -23)

=0.996 * 10^(-14)

What is the secondary consumer in the gulf of mexico


The secondary consumers like small groupers and triggerfish feed on the primary consumers.

Final answer:

The secondary consumer in the Gulf of Mexico ecosystem is often the red snapper. This fish feeds on primary consumers like small fish and invertebrates such as shrimp.


The secondary consumer in a food chain or web is the organism that feeds on primary consumers. In the Gulf of Mexico, various species can serve as secondary consumers, but a common example is the red snapper. The red snapper primarily feeds on smaller fish and invertebrates such as shrimp, who are primary consumers that feed on producers like phytoplankton and seagrasses.

However, it's essential to understand that food webs can be complex, with some organisms fitting into more than one trophic level depending on their various food sources.

What is a beaker? can you also post a picture of what it ;looks like for me?


It's a piece of glassware used for handling liquids, usually in a laboratory,
although I use one as a coffee cup.

They have markings on the side, like a kitchen measuring cup, so you can
measure different amounts of liquid, and they have a lip for pouring.

They're also usually made of a special type of glass (borosilicate) so that
they won't crack when very hot liquids are poured in.

Here's a picture of a beaker with 200 milliliters of some blue stuff in it.
