Answer:
64 kg
Explanation:
The computation of the number of kg need to ordered is shown below:
As we know that

Now as we know that
1 mole of
generated from 1 mole of 
Now
26g of
generated from 64g of 
And,
26kg of
generated from
= 
= 64kg 
Hence, the number of kg that required for ordering the calcium carbide is 64 kg
Depends on where you live but generally speaking it is either June or July
