Answer
C3H8O and 60.0 g/mol
Work Step by Step
Now that you know this, you would need to find the molar mass of each element in order to calculate the total molar mass.
C = 12.0107 g/mol
H = 1.00794 g/mol
O = 15.9994 g/mol
Remember that there were 3 Carbon molecules, so multiply 12.0107 x 3 = 36.0321 g/mol
Remember that there were 8 Hydrogen molecules, so multiply 1.00794 x 8 = 8.06352 g/mol
You already know that 1 Oxygen molecule is equivalent to 15.9994 g/mol, so now all you have to do is add them all up.
36.0321 + 8.06352 + 15.9994 = 60.09502
Relatively when rounding, they would be 36 + 8 + 15 = 59
All in all, your answer would be 60.0 g/mol
