The mass in grams of 6.0 mol hydrogen gas (contains h2) is
Answer: The mass of hydrogen gas is 12 grams
Explanation:
To calculate the number of moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)
Molar mass of hydrogen gas = 2 g/mol
Moles of hydrogen gas = 6.0 moles
Putting values in above equation, we get:
\(6.0mol=\frac{\text{Mass of hydrogen gas}}{2g/mol}\\\\\text{Mass of hydrogen gas}=(6.0mol\times 2g/mol)=12g\)
Hence, the mass of hydrogen gas is 12 grams
