Question

Volume at STP, occupied by 1023 molecules of oxygen is
A 3.72 X103 ml
B 7.44X103 ml
C 14.88X106 ml
D 21.88X 106 ml

Answer 1

Explanation:

• molecules of 1 mole = 6.022×10^23

• 1023 molecules =1023/6.022×10^23 moles

• 1mole = 22400ml

• volume occupied by 1023 molecules at STP = 22400 × 1023/6.022×10^23

• now u can calculate it..
