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

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
