Question

What volume would 4 moles of gas occupy at stp? do this without a calculator. you may need to use longhand calculations. the question is designed to tolerate reasonable rounding?

Answer 1

v.o.g = moles × s. t . p
= 4 × 22.4
22.4
4
= 89 .6

OR

split it up; what you need to find is 22.4 × 4
So 22 x 4 = 88
0.4 × 4 = 1.6
88 + 1.6 = 89.6
