Question

An aqueous solution contains 5.00 g of NaNO$_2$ dissolved in 200.0 mL of water. The solution has a density of 1.0115 g/mL. The density of water is 1.000 g/mL, and the density for sodium nitrite is 2.168 g/mL. Assume that the volumes are not additive. Identify the following concentrations of the solution using appropriate dimensional analysis to determine each variable: w/w% w/v% v/v% M

Step 1

Given: Mass of NaNO3 = 5.00 g Volume of water = 200.0 mL Density of solution = 1.001 g/mL Total mass of solution = mass of NaNO3 + mass of water Total mass of solution = 5.00 g + 200.0 g = 205.00 g Weight percentage (w/w%) = (mass of NaNO3 / total mass of Show more…
