Question

How many molecules of N2 are in a 500ml container at 780mm Hg and 135 degree celcius?​

Answer 1

Answer:

9.23×10^21

Explanation:

PV = nRT

(780 Torr) (0.500 Litres) = n (62.4 Torr-Litres/mol-K)(408 Kelvin)

n = 0.0153 moles

using avagadro's number:

0.0153 moles @ 6.022 e23 molecules /mol = 9.22 e21 molecules

your answer is

9.23 x 10^21
