Acetylene gas, C2H2, releases large quantities of heat when it burns, making it ideal for welding applications. This gas is generated by reacting calcium carbide with excess water. Calcium hydroxide is a byproduct of this reaction. If you needed 26kg of acetylene to fill a cylinder, how many kg calcium carbide would you need to order?

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
