(a)
Interpretation:
The mass percent of silver nitrate in unknown mixture has to be calculated.
Concept introduction:
The mass percentage of compound can be calculated by dividing the calculated mass of the substance to the total mass of the sample whole multiplied by 100.
The mass percent can be calculated with formula,
Mass percent(in percentage)=Calculated mass(in grams)total mass(in grams)×100
Molarity can be defined as the moles of solute to the volume of the solution (in litres). The molarity of a solution can be given by the formula,
Molarity(M)=Moles of solute(in mol)Volume of solution(in L)
Molar mass = Mass Mole
(b)
Interpretation:
The uncertainty in mass of silver nitrate in unknown mixture has to be calculated.
