Answer:
Approximately 51 grams
Explanation:
First find the molar mass of carbon, which is around 12 grams by looking at a periodic table. Then, multiply 12 by 4 since there are 4 carbons. Next, find the molar mass of hydrogen, which is around 1 gram. Multiply it by 3 since there are 3 hydrogens. Finally add up both of the molar masses to get the total molar mass, which is 51 grams.
12g (4) + 1g (3)= 51 g
