3. What weight of calcium bicanbonate should be heated to obtain 2.4 x 10 to the power 23 molecules of CO₂. |
| Answer» TION:Chemical reaction involved is:CaCO 3 →CaO+CO 2 MOLAR mass of CaCO 3 =40+12+16×3=100 gAccording to the balanced reaction 100 g of CaCO 3 PRODUCES 1 mol of CO 2 i.e. 22.4 L at STP.∴50 g CaCO 3 will produce 10022.4 ×50=11.2 L CO 2 at STP. | |
