Acetylene gas c2h2 undergoes combustion to produce carbon dioxide and water vapor how many grams of water are produced by the same amount of c2h2?

The amount of water produced in the given reaction is grams.

Explanation:

Let us assume that the initial amount of acetylene gas given be 'x' grams. Now, to calculate the number of moles, we will use the formula:

  ....(1)

Given mass of acetylene = x grams

Molar mass of acetylene = 26 g/mol

Putting values in above equation, we get:

The reaction of combustion of acetylene is given by the equation:

By Stoichiometry of the reaction:

2 moles of acetylene produces 2 moles of water.

So, moles of acetylene will produce = moles of water.

Now, to calculate the amount of water produced, we use equation 1:

Molar mass of water = 18 g/mol

Moles of water =

Putting values in equation 1, we get:

grams

a is the correct answer
