Question

One mole of particles lowers the freezing point of 1,000 g of water by 1.76ºc. what is the freezing point of a solution containing one mole of nano3 in 1,000 g of water

Answer 1

-3.52ºc
Sodium nitrate (NaNO3) when dissolved in water breaks into two ions, so one mole of NaNO3 in 1,000 g of water actually provides two moles worth of particles. So the freezing point depression will be 2*1.76ºc = 3.52ºc. And since the freezing po
