What will be the molarity of the resulting solutions made by mixing the following? Assume that volumes are additive.
(a) $175 \mathrm{~mL}$ of $3.0 \mathrm{M} \mathrm{H}_{2} \mathrm{SO}_{4}$ with $275 \mathrm{~mL}_{2}$ of $\mathrm{H}_{2} \mathrm{O}$
(b) $350 \mathrm{~mL}$ of $0.10 \mathrm{M} \mathrm{CuSO}_{4}$ with $150 \mathrm{~mL}$ of $\mathrm{H}_{2} \mathrm{O}$
(c) $50.0 \mathrm{~mL}$ of $0.250 \mathrm{M} \mathrm{HCl}$ with $25.0 \mathrm{~mL}$ of $0.500 \mathrm{M} \mathrm{HCl}$
