Which is the strongest electrolyte between this 2?

Question

Ok we have:
* 10g of Hg(NO3)2 in 1000g of water (freezing point=-0.162 °C)
* 10g of HgCl2 in 1000g of water (freezing point=-0.0685°C)

With this information, I have to determine which is the strongest electrolyte.

***Please tell me if I'm doing it right***: because both have similar molalities, I calculated the van 't hoff factor (i) in both solutions.
i Hg(NO3)2 = 2.84 (ideally 3 with complete dissociation)
i HgCl2 = 1.00 (ideally 3 with complete dissociation)

So I came to the conclusion that Hg(NO3)2 was the strongest electrolyte because it was the one that produced more total particles and it was the closest one to the ideality.
Am I right or completely wrong? Thanks

You are exactly right.
