Answer: Molar mass is 120g/mol (120 gram per mole)
Explanation: Molar mass is the sum of all the molecular masses of the elements in a compound. Molar mass is the mass in grams of one mole of a substance.
C4H8O4
In this compound,
C is carbon with molar mass of 12g. Since there are four atoms of it, we now multiply the molar mass by 4, giving us
C4 = 12 x 4 = 48g
H is hydrogen with molar mass of 1g. Since there are eight atoms of it, we now multiply the molar mass by 8, giving us
H8 = 1 x 8 = 8g
O is oxygen with molar mass of 16g. Since there are four atoms of it, we now multiply the molar mass by 4, giving us
O4 = 16 x 4 = 64g
Adding all together, we have
C4H8O4 = (12 x 4) + (1 x 8) + (16 x 4)
= 48 + 8 + 64
= 120g/mol
The molar mass of C4H8O4 is 120g/mol
