Calculate the mass in grams of 0.16 mole of `H_2S`.

Explanation

To calculate the mass in grams of 0.16 moles of H₂S (hydrogen sulfide), we can follow these steps:

### Step 1: Determine the Molar Mass of H₂S
- The molar mass of a compound is calculated by adding the atomic masses of all the atoms in the molecule.
- H₂S consists of:
- 2 hydrogen (H) atoms
- 1 sulfur (S) atom

Using the atomic masses:
- Atomic mass of hydrogen (H) = 1 g/mol
- Atomic mass of sulfur (S) = 32 g/mol

Calculating the molar mass:
\[ \text{Molar mass of H₂S} = (2 \times 1) + (1 \times 32) = 2 + 32 = 34 \text{ g/mol} \]

### Step 2: Use the Formula to Calculate Mass
- The formula to calculate mass from moles and molar mass is:
\[ \text{Mass} = \text{Moles} \times \text{Molar Mass} \]
- We know:
- Moles of H₂S = 0.16 moles
- Molar mass of H₂S = 34 g/mol

Now substituting the values:
\[ \text{Mass of H₂S} = 0.16 \text{ moles} \times 34 \text{ g/mol} = 5.44 \text{ grams} \]

### Final Answer
The mass of 0.16 moles of H₂S is **5.44 grams**.
