Question

The atomic mass of carbon is 12.01, hydrogen is 1.01, and oxygen is 16.00. What is the molar mass of glucose `C_6H_12O_6`?

Answer 1

Molar Mas of Glucose is 180 g/mol

Explanation:

If we look at the Chemical formula of Glucose , it is `C_6` `H_12` `O_6`.

One mole of Glucose has 6 moles of Carbon atoms, 12 moles of Hydrogen atoms and 6 moles of Oxygen atoms. Molar mass of each element can be determined from the periodic table.

Molar mass of Carbon ( one mole of Carbon has mass ) = 12.01 g/mol.
Molar mass of Hydrogen is ( one mole of Hydrogen has mass ) = 1.0008 g/mol
Molar mass of Oxygen is ( one mole of Oxygen has mass ) = 16 g/mol

Molar mass of Glucose = 6 mol x 12.01 g/mol + 12 mol x 1.008 g/mol + 6 mol x 16 g/mol

Molar mass of Glucose = 180.156 g/ mol. or 180 g/mol.
