Question

calculate the volume at S.T.P.of 8.5×10`4 kg of oxygen.​

Answer 1

Hi friend,

here is your answer

Answer:

molar mass of oxygen = 16×2 = 32

so, 32×10^-3

No. of moles of oxygen molecule = given mass / molar mass

given mass = 8.5×10^-4

molar mass = 32×10^-3

No. of moles = 0.02656

so, volume of oxygen molecule of mass 8.5×10-4 kg at STP is 0.02656 × 22.4

= 0.5949 litre
