Two equations in two unknowns. Solve the two simultaneously.
Let X = g NaCl
and Y = g KCl
equation 1 is X + Y = 1 g
Equation 2 comes here. mm stands for molar mass.
X(mm AgCl/mm NaCl) + Y(mm AgCl/mm KCl) = 2 g
Solve for X and Y in grams NaCl and grams KCl.
Then convert g each to mols and calculate the ratio mols one to the other. Post your work if you get stuck.
2g AgCl is obtainded by adding an excess of AgNO3 solution to a solution containing 1g of a mixture of NaCl and KCl.What is the ratio of moles of two salts in the mixture?
