Question

calculate the active mass of 1mole of SO2 gas at STP?​

Answer 1

Answer:

At STP a mole of oxygen molecules will occupy 22.4 litre of volume. 1 mole of O2 molecules have at =2×16=32gm. 32gm of active mass could occupy 22.4 litres Hence 5.6 litres would occupy (5.6/22.4)×32=8gms.

Answer 2

Answer:

HIII!!

Explanation:

ACTIVE MASS : GIVEN WIEGHT / MOLECULAR MASS × volume .

Active mass= 0.64/ 64 × 10 = 10^-3
