Chapter 6, Problem 26E

Calculate the number of moles and the mass of the solute in each of the following solutions:

(a) 2.00 L of $18.5M{\text{H}}_2{\text{SO}}_4$, concentrated sulfuric acid

(b) 100.0 mL of $3.8\times {10}^{-5}M\text{NaCN}$, the minimum lethal concentration of sodium cyanide in blood serum

(c) 5.50 L of 13.3 $M{\text{H}}_2\text{CO}$, the formaldehyde used to “fix” tissue samples

(d) 325 mL of $\text{1}\text{.8}\times {\text{10}}^{-6}M{\text{FeSO}}_4$, the minimum concentration of iron sulfate detectable by taste in drinking water
