how many moles of ch4 are in 64.2 g ch4?\n64.2 g ch4 | 1 mol ch4\n| 16.05 g ch4\n? moles ch4
Answer
Explanation:
Step1: Identify conversion factor
We know that 1 mole of $CH_4$ has a mass of 16.05 g. So the conversion factor is $\frac{1\ mol\ CH_4}{16.05\ g\ CH_4}$.
Step2: Calculate moles
We multiply the given mass of $CH_4$ by the conversion factor. So, $n=\frac{64.2\ g\ CH_4\times1\ mol\ CH_4}{16.05\ g\ CH_4}$. $n = \frac{64.2}{16.05}\ mol= 4.00\ mol$
Answer:
4.00 moles $CH_4$
