Question

Number of moles of glucose in 152g of glucose

Answer 1

The answer is (152/180) moles

Answer 2

 molar mass, sometimes referred to as molecular weight, is the mass of one mole of a substance and is usually expressed in grams. 

Therefore, 



In general,



Calculation of molar mass of glucose (C6H12O6) 

The molar mass of glucose can be calculated from the molar masses of individual atoms present in it. From the molecular formula, C6H12O6, one can find there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in one molecule of glucose. 

Molar mass of C = 12 g mol-1

Molar mass of H = 1 g mol-1 

Molar mass of O = 12 g mol-1 

Therefore,

Molar mass of C6H12O6=(6x12) + (12x1) + (6x16) = 72 + 12 + 96 = 180 g mol-1
