Question

find the mass of cuco3 required to produce 11.3litre of co2 at standard temperature and pressure​

Answer 1

Answer:

Cuco3 gives us cuo + CO2

So half mole of cuco3 is required

So 1/2*100

Is equals to 50g

Answer 2

Answer:

molecular mass of cuco3=123.5g

since,123.5g of cuco3produces=22.4litre

i.e for producing 22.4 litre of co2 required =123.5g

there for,for producing 11.3litre of co2 required=123.5*11.3/22.4=62.30g of cuco3
