Im so sorry i don’t know I just need to answer 2 questions for me to be Able to ask
the correct answer is Carbon. I put hydrocarbon and it was wrong Carbon is 100% correct.
Answer:
NH4Cl > Li2SO4 > CoCl3
Explanation:
Let us recall that the freezing point depression depends on the molality of the solution and the number of particles present.
Let us also recall that freezing point depression is a colligative property. It depends on the number of particles present in solution.
Usually, the more the number of particles present, the lower the freezing point. Hence, NH4Cl which has only two particles will have the highest freezing point while CoCl3 which has four particles will have the lowest freezing point.
Mass = mole x molar mass
Explanation:
The mole of the substance used in the bakanced eqn multipled by its molar mass equals to Its mass
