A recent study found the median level of lead ion concentration in Canadian tap water is 2.3 x 10 -8 mol/ L. Calculate the mass in grams of lead consumed when an individual drinks 2.8 L of water. Record final answer in 2 digits using scientific notation.
Evidence
volume of solution = 10.00 mL
mass of beaker = 79.54 g
mass of beaker and residue = 87.43 g
From this data calculate the molar concentration of the original sodium nitrate solution.
