Question

How many grams of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)?

Answer 1

`55.1657` grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)

Step-by-step explanation:

The molecular weight of acetylene is 26.04 g/mol

Molecular weight of carbon is equal to 12.011 g/mol

Two carbon atom produces one acetylene molecule.

Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,

Amount of carbon required to produce 59.8 grams of acetylene

`(2*12.011)/(26.04) * 59.8 \\= 55.1657`grams/mol

`55.1657` grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
