Final answer:
The mass of 5.66 moles of methane (CH4) is calculated by multiplying the number of moles by the molar mass of methane, which is 16.04 g/mol, resulting in 90.7464 grams.
Step-by-step explanation:
The mass of 5.66 moles of methane, CH4, can be calculated by multiplying the number of moles by the molar mass of methane. Methane has a molar mass of approximately 16.04 g/mol (12.01 g/mol for carbon and 1.008 g/mol for each of the 4 hydrogen atoms). To find the mass, we use the formula: mass = moles × molar mass.
So, for 5.66 moles of CH4, the calculation would be:
Mass = 5.66 moles × 16.04 g/mol = 90.7464 grams
Therefore, the mass of 5.66 moles of methane is 90.7464 grams.
Methane is a simple hydrocarbon with the chemical formula CH4. It's the simplest alkane and the primary component of natural gas, often found in underground reservoirs. Methane is colorless, odorless, and highly flammable.
