you need to make 20ml of a 20% glucose solution. I need to calculate the amount of glucose and water needed. I know that the M.W is 180.16 for glucose. Would I multiply 20ml times 20 percent first? Thank you!

1 liter would contain .2 moles of glucose
So, 20ml would contain .2*.02 = .004 moles
.04 moles = 0.72g glucose
So, 20ml would contain .2*.02 = .004 moles
.04 moles = 0.72g glucose
