: First find the given information – 10g of NaCl 100.0mL of water Next find equation(s) that will be needed – For %(mass/volume): Concentration %(m/v) = Mass(g)/Volume(mL) X 100% Substitute givensè C%(m/v)= 10g/100.0 mL X 100% = 10% (m/v) For molarity: M= moles/volume(L) Looking at the formula, we have volume, but it is in milliliters not liters so we need to convert into liters: 10mL X 1L/1000mL = 0.10 L Also, the formula has moles and we are given grams, therefore we need to convert grams of NaCl to moles of NaCl. Looking at the atomic masses for Na (22.990) and Cl (35.453), the conversion needed is 58.443g/1 mole. Now we can convert: 10g NaCl x 1 mole NaCl/ 58.443g NaCl = .1701107 è 0.17 mol NaCl Substitute into the equation: M = .17 mol NaCl/ 0.10L = 1.7 M So the answers to this problem of concentration and molarity are 10% concentration(m/v) and 1.7 M for molarity.
