Question

CH4 + 2 02- CO2 + 2 H20

How many moles of carbon dioxide are produced from the combustion of 110 g of CH4?

Answer 1

Answer: 32 grams of O2.

Step-by-step explanation:

First, find the molar mass of methane

C = (1 * 12) = 12

H = (4 * 1) = 4

Molar mass is 16 g/mole

So, 8 grams of methane is 1/2 a mole

Since the ratio of methane to oxygen is 1:2, you need twice as many moles of O2, in this case, that's 1 mole of O2.

Find out how many grams is 1 mole of O2

The molar mass of O2 is

O2 = 2*16 = 32 grams per mole
