Question

The molar mass of methane is 16.04 g/mol. Calculate the number of moles of methan burned in the experiment.

Answer 1

To calculate the number of moles of methane burned in the experiment, divide the mass by the molar mass.

Step-by-step explanation:

To calculate the number of moles of methane burned in the experiment, we need to know the mass of methane burned. Given that the molar mass of methane is 16.04 g/mol, we can use the formula mass = moles x molar mass. Let's say the mass of methane burned is 32 g. Divide the mass by the molar mass to get the number of moles:

moles = mass / molar mass = 32 g / 16.04 g/mol ≈ 1.995 mol

Answer 2

Given:

Molar mass of methane is 16.04 g/mol

Required:

Number of moles burned in the experiment

Solution:

The data is lacking, however if you are given a mass of methane sample, say for example 50g of methane then,

Number of moles = mass / molar mass = 50g/16.04 g/mol = 3.117mol
