Question: 0.2ml glucose solution. Molar mass of glucose = 180 g/mol How many moles? If it was a mass in grams it would be easy: n = mass/molar mass But what do I do now its a volume? Can I still use the same relationship, since grams is equivalent to ml isnt it? If yes, then what does the unit of 'n' become...ml/mol? Please help. Thanks.
