Question

Ethane (C2H6) reacts with oxygen (O2) to produce water and carbon dioxide (CO2). How many grams of carbon dioxide are produced when 294 grams of ethane are reacted

Answer 1

This equation tells us that for every 1 mole of C2H6, 2 moles of CO2 are produced. To find the number of moles of C2H6 in 294 grams, we need to use the molar mass of C2H6, which is 30.07 g/mol.

294 g C2H6 / 30.07 g/mol = 9.78 moles of C2H6

Since two moles of CO2 are produced for every one mole of C2H6, we can calculate the number of moles of CO2 by multiplying the number of moles of C2H6 by 2:

9.78 moles C2H6 x 2 moles CO2/1 mole C2H6 = 19.56 moles CO2

To find the number of grams of CO2, we need to use the molar mass of CO2, which is 44.01 g/mol

19.56 moles of CO2 x 44.01 g/mol = 864.8g CO2

So, 864.8 grams of carbon dioxide are produced when 294 grams of ethane are reacted.
