Question

The freezing point of 1% aqueous solution of calcium nitrate will be​

Answer 1

Answer:

-0.3 °C

Explanation:

The formula for calculating the freezing point depression #ΔT_"f"#

of an ionic solute is

#color(blue)(bar(ul(|color(white)(a/a)ΔT_"f" = iK_text(f)bcolor(white)(a/a)|)))" "#

Answer 2

Answer:

272.89 K

Explanation:

We are given that Ca(NO3)2 is present in 1 % solution, which means that 1.0 gram of calcium nitrate is present in 100 gram of the solution.
