Heterogeneous - hetero means the same. Therefore the answer is something of the same area.
While the water, the vinegar and the dye - are made of the same things (water) they are not the same.
So, I would infer the answer to be the mixture of gases in the air used to inflate a flattened bicycle tire because they are the same thing through and through but, with different molecule structures.

Answer:
The molarity of the Pb(NO3)2 solution is 0.24 M
Explanation:
Assuming there was no loss during filtration, we can calculated amount of moles Pb(NO3)2 from the 13.25 g of PbCl2 ussing molar mass of PbCl2
13.25 g / 278.1 g = 0.04 moles of PbCl2
According balanced equation 2NaCl + Pb(NO3)2 = 2NaNO3 + PbCl2, 1 mol of Pb(NO3)2 produces 1 mol of PbCl2. So, 0.04 moles of Pb(NO3)2 produces PbCl2
Molarity is = moles of solute/volumen of solution (L)=0.04/0.2= 0.24
I hope my answer helps you
