An aqueous solution contains the amino acid glycine (nh2ch2cooh). assuming that the acid does not ionize in water, calculate the molality of the solution if it freezes at −2.05°c. the freezing point depression constant for water is 1.86°c/m.

The molality of the solution is 1.10 m/kg

Explanation:

Colligative property:  freezing point depression.

ΔT = Kf. m

ΔT = T°fussion pure solvent - T° fussion solution

Kf = depression constant for water

0°C - (-2.05°C) = 1.86 °C/m . m

2.05°C = 1.86°C/m . m

2.05°C / 1.86° m/°C = m  → 1.10 m/kg

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
