Question

A glucose (C6H12O6) solution is 2.5% glucose by mass. If the density of the
solution is 1.10 g/mL, what is the molarity of glucose/water solution?

Answer 1

assume 1000grams. Then glucose is 25grams, and water 975 grams.
volume+ 1000/1.1=909 ml

molarity= (25/molmassglucose)/.909

Answer 2

How did you get the amount of water?

Answer 3

volume+ 1000/1.1=909 ml? I don't get this...

I understand how you got the water

Answer 4

you have 1000 total grams, the density is 1.1g/ml, so volume= 1000/1.1 ml

Answer 5

Oh... I get it now! Thank you very much. Your help is greatly appreciated.
