Acid rain is a worldwide environmental issue. You collect a sample of potentially acidic rainwater and submitted to analyze. Several acidic ions were found in the solutions and the concentrations were shown below: Total inorganic carbon = 0.1 mg-C/L [Cl-] = 0.7 mg/L as Cl [NO3-] = 0.6 mg/L as N [SO42-] = 0.5 mg/L as S (Note: TIC is the total concentration of carbon dioxide) Please calculate the pH value of the rainwater.
Asuume magnesium exists in three isotopes: Mg-24, Mg-25 and Mg-26. If a sample of magnesium contains 10 million atoms, what is the total mass of the sample in amu?
