Question

448 litre mixture of O2 and CO2 is in the ratio 2 is to 3 at NTP find the number of moles of O2 gas and number of molecules of o2​

Answer 1

Explanation:

Pressure= 2 atm

temperature= 273K

volume= 44.8cm

3

=44.* litre

so,By PV=nRT

n=

RT

PV

mole=

0.0821×273

2×44.8

so, no of moles= 3.998=4

hence, 4×6.023×10

23

=24.08×10

23
