Which one is the volume of 1g of oxygen gas at STP?
(i) 0.7 L
(ii) 4.8 L (iii) 1.4 L (iv) 1.2 L.

Text Solution

Verified by Experts

(i) Gram-molecular mass of oxygen gas at STP is 32g
`therefore` At STP, volume 32g of oxygen gas=22.4 L
`therefore` At STP volume of 1 g of oxygen gas `=(22.4)/(32)L=0.7L`
The volume of 1g of oxygen gas at STP is 0.7 L.
