1.) For the reaction C + 2H2 → CH4, how many moles of hydrogen are needed to make 153.2 grams of methane, CH4 ?

Round your answer to the nearest tenth. If you 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.:
