given 4.01 g of ch4, determine the number of moles of ch4. 1 mol ch4 = 16.04 g ch4 ? mol ch4 = 4.01 g ch4…

given 4.01 g of ch4, determine the number of moles of ch4. 1 mol ch4 = 16.04 g ch4 ? mol ch4 = 4.01 g ch4 round your answer to two decimal places.

given 4.01 g of ch4, determine the number of moles of ch4. 1 mol ch4 = 16.04 g ch4 ? mol ch4 = 4.01 g ch4 round your answer to two decimal places.

Answer

Explanation:

Step1: Recall mole - mass formula

The formula to calculate the number of moles $n$ is $n=\frac{m}{M}$, where $m$ is the mass and $M$ is the molar mass. Here, $m = 4.01$ g and $M=16.04$ g/mol for $CH_4$.

Step2: Calculate the number of moles

$n=\frac{4.01}{16.04}$ $n = 0.25$ mol

Answer:

$0.25$
