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.

Answers

Answer:

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

Explanation:

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.

Explanation:

Water

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.
