Question

x grams of caco3 is decomposed and CO2 gas liberated is passed over red hot coke. If 11.2 litres of Carbon Monoxide is collected, what is the value of x?

Answer 1

now

= caco3 + heat = cao + co2

BY BALANCING

= IF ONE MOLE OF CACO3 IS DECOMPOSED THEN 0ONE MOLE CO2 IS PRODUCED

= NOW NO OF MOLES = 11.2L/ 22.4L

MOLES OF CO2 = 0.5

= NOW 0.5 MOLE OF CACO3 IS PRODUCED

MOLAR MASS OF CACO3 = X = 0.5 x ( 40+12+48)

= X = 0.5x 100g

x = 50g
