Question

How many molecules of an ideal gas are there in 1 ml of the gas if the temperature is 27c and the pressure is 3 atm

Answer 1

Answer:use PV=nRT

Now we have to find n therefore

n=PV/RT

Substitute the values

n=3×1/8.314×300

= 0.12079×6.023 ×10²³

0.000724×10²³

Therefore 7.24×10¹⁹

Explanation:temperature =27+273=300
