Question

calculate volume of co2gas in liter produced at step by heating 25g caco3?

​

Answer 1

Follow these steps :-

1. moles = mass / molecular mass = gas volume / volume of 1 mole.
2. mass / molecular mass = gas volume / volume of 1 mole.
3. molecular mass = mass x volume of 1 mole/volume.
4. therefore at RTP: Mr = mass(g) x 24 / V(dm3)
