Put the following glucose solutions in order of least concentrated (A) to most concentrated (E)

10 grams glucose in 75 millilitres of water
600 mM glucose
5 mg in 1 mL water
7.5 mM glucose in 10 mM NaCl
10 % (w/v) glucose
glucose = 180mw

molar mass of glucose = 180 g/mol

10g in 75 mL is (10/180)/0.075 = 0.74 M
600 mM = .6 M
5mg in 1 mL = (5/180)/1 = 0.028 M
10%w/v = 10g/100mL = (10/180)/0.1 = 0.75 M

in order

5mg in 1 mL = (5/180)/1 = 0.028 M
600 mM = .6 M
10g in 75 mL is (10/180)/0.075 = 0.74 M
10%w/v = 10g/100mL = (10/180)/0.1 = 0.75 M

7.5 mM glucose in 10 mM NaCl is not clear--equal volumes of each?
don't know what mw is
