Question

For the reaction C + 2H₂ → CH₄, how many grams of hydrogen are required to produce 2.2 moles of methane, CH₄?

Round your answer to the nearest tenth. If your answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Answer 1

$H_2:CH_4=2:1$

2 moles of $CH_4$ requires $\frac{2}{1}×2.2$

$=4.4$ moles of Hydrogen

Molar mass of $H_2$ $=4.4×2$

$=8.8g$
