many moles?
[Round your answer to the nearest hundredth (0.01)]

Answer 1

1.83moles

Step-by-step explanation:

Given parameters:

Mass of methane given = 29.2g

Unknown:

Number of moles = ?

Solution:

To find the number of moles in this mass of a compound;

Number of moles =
`(mass)/(molar mass)`

Molar mass of CH₄ = 12 + 4(1) = 16g/mol

Now;

Number of moles =
`(29.2)/(16)` = 1.83moles
