Question

The concentration of glucose in the aqueous fluid of the spine is 75.0 mg/100mL of fluid. What is the molar concentration of glucose in spinal fluid?

Answer 1

\[\huge \rho = \frac{ m }{ V }=\frac{ M \times n }{ V }=C \times M\]
Can you solve it from here?

Answer 2

Trying it now

Answer 3

0.075g/180.16g/mol = 4.16x10^-4 mol glucose
100mL = 0.1 L
4.16x10^-4 mol / 0.1 L = 4.16x10^-3 M

is this right?

Answer 4

Looks correct to me.

Answer 5

Ok thank you

Answer 6

No problem at all.
