Determine the number of grams of C4H10 that are required to completely react to produce 8.70 mol of CO2 according to the following combustion reaction:
2 C4H10(g) + 13 O2(g) --> 8 CO2 (g) + 10 H2O(g)
Please show step by step and how to put into parentheses ex: given x (amount over amount) x (amount over amount) x (amount over amount) = answer.
