Answer to Question #195722 in Organic Chemistry for Masego

Question

You have 10 mL of an 8% aqueous solution of H2Cl6Pt. (a) Calculate the platinum in this solution as well as (b) the molar concentration of the platinum in this solution. The density of the solution is 1.05 kg.L-1.

Answer 1

Mass of solution $=1.05×0.01=0.0105Kg= 10.5g$

Moles = $\frac{10.5}{409.81}=0.026$

Molarity $=\frac{0.026}{0.01}=2.6M$
