Question

Which of the following has maximum mass ?a) 0.1g atom of carbon (b)0.1mol of ammonia (c) 1120cc of carbon dioxide

Answer 1

Answer:

correct option is (d)

Explanation:

a) 0.1g atom of carbon = 0.1 mole of C = 0.1 x 12g = 1.2 g

b) 0.1 mole of ammonia = 0.1 x 17 = 1.7 g

c) 6.02 x 10^22 molecules of hydrogen

= (6.02 x 10^22)/(6.02 x 10^23)

= 0.1

0.1 mole Hydrogen = 0.1 x 2 = 0.2 g

d) 1120cc of CO2: Mole = 1120/22400 = 1/20 mole

mass = 1/20 x 44 = 2.2g
