2C2H6 + 7O2 --> 4CO2 + 6H20 given 7.5 X 10 to the 3rd of C2H6 how many grams of CO2 is emitted

the 7.5 x 10 to the third is 7500 what do i do to figure out the rest

2 answers

4/2 = 2 mols of CO2 for every mol of C2H6

mol of C2H6 = 2*12+6 = 30 g
mol of CO2 = 12+32 = 44 g

7500 * 2 * 44/30
The following procedure will work these stoichiometry problems.
1. Write and balance the equation. You have that.

2. Convert What you have (C2H6) to mols. mols = grams/molar mass = ?

3. Using the coefficients in the balanced equation, convert mols what you have (C2H6) to mols of what you want (CO2).

4. Now convert mols of what you want (CO2 in this case) to grams. g = mols x molar mass = ?
