Question

How many moles of CH4 is equivalent to 25.1 g of CH4 (Mw. 16.04 g/mol)?

Answer 1

n(CH4)=m/Mw

$n = \frac{25.1}{16.04} = 1.5648 \: mol$
answer: 1.56 mol

Answer 2

The number of moles of CH₄ that is equivalent to 25.1g of CH₄ is 1.56 moles

From the question,

We are the determine the number of moles of CH₄ (Methane) that is equivalent to 25.1 g of CH₄

To determine the number of moles of methane equivalent to the given mass,

We will use the formula

$Number\ of\ moles = \frac{Mass}{Molar\ mass}$

From the question.

Mass = 25.1 g, and

Molar mass = 16.04 g/mol

Putting these values into the equation, we get

$Number\ of\ moles = \frac{25.1}{16.04}$

∴ Number of moles = 1.56 moles

Hence, the number of moles of CH₄ that is equivalent to 25.1g of CH₄ is 1.56 moles
