We did this type of problem yesterday !

Answer 3

i might have an idea how to do this
91.0 = mass NaCl x 100/315
mass NaCl = 286.7 g
moles NaCl = 286.7/58.44 g/mol=4.90
moles glucose = 1.5 x 4.5 = 6.8
???

Answer 4

4.5 M means 4.5 moles per liters. So no of moles in 1.5 liters is simply 1.5*4.5 = 6.75 moles

Answer 5

yeah i was rounding
