Answer:
C₆H₈O₇ = 192 g/mol
Step-by-step explanation:
Molar mass is the sum of the atomic weight of the atoms present in compound.
Formula of citric acid:
C₆H₈O₇
Atomic weight of hydrogen = 1 amu
Atomic weight of carbon = 12 amu
Atomic weight of oxygen = 16 amu
C₆ = 6 × 12 = 72 g/mol
H₈ = 8 × 1 = 8 g/mol
O₇ = 7 × 16 = 112 g/mol
C₆H₈O₇ = 72 g/mol + 8 g/mol + 112 g/mol
C₆H₈O₇ = 192 g/mol
