Question

The number of molecules in a gas at pressure 1.64×10^-3 atmospheres and temperature 200k having the volume 1 cc are.
1)6.02×10^16
2)2.63×10^16
3)3.01×10^19
4)12.04×10^19​

Answer 1

answer:1

explanation:

pv=nrt

where v is volume in litre

r is 0.08 latm

after solving it no. of mole= 1.025*10^-7

then convert into no. of molecule by multiply with Avogadro number

no. of molecule =6.02*10^16(approx)
