When 22.4L of H2g is mixed with 11.2 of cl2 g each at STP the moles of stp the moles of hcl g formed is equal to

Answer»

This is the question of limiting reactant
22.4 liter of H2 GIVES 22.4 liter of hcl


And 22.4 liter of CL2 gives 22.4 liter of hcl
1 liter gives 22.4 ÷22.4 liter of hcl
11.2 liter of hcl gives 22.4 ÷ 22.4 ×11.2 liter of hcl
= 11.2 liter of hcl


So cl2 is limiting reactant
11.2 liter of cl2 gives 11.2 liter of hcl
Moles = volume ÷ 22.4
Moles = 11.2 ÷22.4
Moles = 0.5 moles

And its MASS is mass = mole × MOLECULAR mass
Mass = 0.5 × 36.5
Mass in gram = 18.25
