The molar mass of c7h16 and the molar mass of cac03 contain approximately the same number of

The molar mass of C7H16 and the molar mass of CaC03 contain approximately the same number of grams per mol (g/mol)

Explanation:

C7H16 is an alkane group compound known as Heptane. The chemical formula can also be represented as H₃C(CH₂)₅CH₃. The molar mass can be calculated as the sum of the atomic mass present in the compound. It molar mass can be calculated as follow :

atomic mass of carbon = 12.0107

atomic mass of hydrogen = 1.00784

From the compound, carbon has 7 atom = 12.0107 × 7 = 84.074

Hydrogen has 16 atom = 1.00784 × 16 = 16.12544

sum of the atomic masses = 16.12544 + 84.074 = 100.19944

molar mass = 100.19944g/mol

CaCO3 is known as calcium carbonate. They are mainly found in limestone .  The molar mass is calculated as the sum of the atomic mass present in the compound. it can be calculates as follows ;

atomic mass of calcium = 40.078

atomic mas of carbon = 12.0107

atomic mass of oxygen = 15.999

From the compound, calcium has 1 atom = 40.078

carbon has 1 atom = 12.0107

oxygen has 3 atom = 15.999 × 3 = 47.997

sum of the atomic masses = 40.078 + 12.0107 + 47.997 = 100.0857

molar mass  = 100.0857g/mol  

From the calculation above you will notice both compound contain approximately the same grams per mol . Both have approximately the same amount of molar mass.

Molar mass of calcium carbonate = 100.0857g/mol

Molar mass of Heptane =  100.19944g/mol
