The molarity of one molal glucose solution having density of 1.2 ~g / mL is
Options
- A0.101 M
- B1.01 M
- C2.01 M
- D0.001 M
Correct answer
B. 1.01 M
Step-by-step solution
d =1.2 ~g ~mL ⁻¹, ~m =1 ~mol ~kg . Let's take 1 ~kg of the solution. aligned & Volume of the solution = mass density & = 1000 ~g 1.2 ~g ~mL ⁻¹ =833.33 ~mL & =0.833 ~L & Number of moles =1.0 ~mol aligned Therefore, molarity = 1.0 ~mol 0.833 ~L =1.20 M 1.01 M
