Question

7.5 g of a gas occupies a volume of 5.6 litres at 0° C and 1 atm pressure. The gas is

विकल्प

• NO

• N₂O

• CO

• CO₂

Answer 1

NO

Explanation:

7.5 g of gas occupies a volume of 5.6 liters at 273 K and 1 atm pressure Therefore, the mass of gas that occupies a volume of 22.4 liters

= `(7.5  "g")/(5.6  "L") xx 22.4` L = 30 g

Molar mass of NO (14 + 16) = 30 g
