Answer:
32.08
Step-by-step explanation:
The molar mass of CH4 (methane) is 16.04 g/mol (1 carbon atom with a molar mass of 12.01 g/mol and 4 hydrogen atoms with a molar mass of 1.008 g/mol each).
To find the number of grams in 2 moles of CH4, we can use the following equation:
mass (in grams) = number of moles × molar mass
Substituting the values, we get:
mass = 2 moles × 16.04 g/mol
mass = 32.08 g
Therefore, 2 moles of CH4 contain 32.08 grams of CH4.
