Expert Solution
Step 1
Here we are mixing NaNO3(aq) and Ca(NO3)2(aq).
Both NaNO3(aq) and Ca(NO3)2(aq) are completely dissolved in water to give respective ions.
1 mol NaNO3(aq) is dissolved in water to form 1 mol Na+(aq) and 1 mol NO3-(aq).
Hence mole ratio = 1/1
Since the coefficient of NO3 in Ca(NO3)2(aq) is 2,
1 mol Ca(NO3)2(aq) is dissolved in water to form 1 mol Ca2+(aq) and 2 mol NO3-(aq).
Hence mole ratio = 2/1
