Question

What volume of CO2 is obtained at STP by heating 4 g of CaCO3

Answer 1

Answer:

Given that ,

mass of CaCO3 , W = 4g

Now ,

CaCO3(s) ------------->CaCO (s) + CO2 (g)

100g 22.4 lit

4g ---------------------------------> ?X

Now ,

X/22.4 lit = 4g/ 100g

=> X= 4/100×22.4lit

=> X = 0.896 lit

=> X= 896 ml

#volume of CO2 obtain = 896 ml
