Step 1
5 g/mol Concentration = 2.5 M Density = 1.10 g/mL Molarity = (58.5 * 2.5) / 1.10 Molarity = 146.25 / 1.10 Molarity = 133.1818 M Show more…

What is the molarity for a solution containing $100 \mathrm{~g}$ of $\mathrm{NaCl}$ made up to 500 mL with distilled water? Assume a gram molecular weight (from periodic table) of approximately 58 grams. a. $3.45 \mathrm{M}$ b. $1.72 \mathrm{M}$ c. $290 \mathrm{M}$ d. $5.27 \mathrm{M}$
Calculate the mass/mass percent concentration for each of the following solutions. (a) 1.25 g $\mathrm{NaCl}$ in $100.0 \mathrm{~g}$ of solution (b) $2.50 \mathrm{~g} \mathrm{~K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}$ in $95.0 \mathrm{~g}$ of solution (c) $10.0 \mathrm{~g} \mathrm{CaCl}_{2}$ in $250.0 \mathrm{~g}$ of solution (d) $65.0 \mathrm{~g} \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}$ in $125.0 \mathrm{~g}$ of solution
