Question

molality of pure water is with solution
​

Answer 1

Answer:

molality of pure water is 55.6

Answer 2

Answer:

Explanation:

Let's say you had  

1 L

of water. At  

25

∘

C

, the density of water is  

0.9970749 g/mL

, so that's  

0.9970749 kg

.

At that amount of water, the number of moles is

997.0749 g

18.0148 g/mol

=

55.348 mols

molality:

mol water

kg water

=  

55.348 mols

0.9970749 kg

=

55.50991407

≈

55.510 m

molarity:

mol water

L water

=

55.348 mols

1 L

≈

55.348 M
