Question

Volume of oxygen at NTP required to completely burn 1 kg of coal ( 100% carbon ) is

a. 22.4 l

b. 1.86 * 1000 l

c. 22.4* 1000 l

d. 1000 l

Answer 1

Volume of oxygen at NTP required to completely burn 1 kg of coal ( 100% carbon ) is. a. 22.4 l. b

Answer 2

Answer:

Mass of C = 1000 g

1 moles C requires 1 mole O₂    to burn.

Thus, 83.34 mole C requires 83.34 moles O₂  

At NTP, 1 mole gas occupies 22.4 litres.

83.34 moles occupies 83.34 × 22.4 = 1.86 × 10³  L
