Ответ:
Molar mass of CH18 =30
Explanation:
CH18
Molar mass of carbon = 12
Molar mass of hydrogen (H) = 1
CH18 = 12 + 1 (18) = 12 +18 = 30
Ответ:
Molar mass = 30 g/ mole CH18
Explanation: The molar mass of CH18 can be calculated by having the sum of the atomic mass of each atom in the compound.
C - 12 (1 ) = 12
H - 1 ( 18 ) = 18
Molar mass = 30 g / mole CH18
