Answer:
The molecular weight of methane (CH4) is 16.04 g/mol. To find the number of moles in a given mass of methane, we can use the following equation:
moles = mass / molecular weight
Plugging in the values:
moles = 5.80 g / 16.04 g/mol
moles = 0.36 moles
Therefore, there are 0.36 moles of methane in 5.80 g of methane.
