Question

How many moles of carbon are in 90g of glucose(C6H12O6)? Assume that the molar mass of glucose is 180g/mol.

Answer 1

To determine, the number of carbon present in a certain amount of glucose, we need to know the chemical formula of glucose to know the number of carbon present for every molecule of carbon. We calculate as follows:

90 g C6H12O6 ( 1 mol / 180 g ) ( 6 mol C / 1 mol C6H12O6 ) = 3 mol C for 90 g glucose
