Question

According to the following balanced equation (CH 4 + 2 O 2 = CO 2 + 2 H 2O), How many moles of H 2O can be produced from 4 moles of CH 4?

A) 2
B) 8
C) 4
D) 12
E) 6

Answer 1

Answer:

In this case 8 moles of H 2O can be produced from 4 moles of CH 4.

Explanation:

We use simple 3 rules for the calculation:

1 mol CH4--------- 2 mol H20

4 mol CH4----------x= (4 mol CH4 x 2 mol H20)/ 1 mol CH4= 8 mol H20
