Question

colligative properties (freezing point depression, boiling point elevation, and osmotic pressure) have been used to determine the molar mass of a solute.
true
false
how did i do?
when osmotic pressure is kept constant, the relationship of molarity (m) and temperature (t) is ___.
dependent on the gas
inversely proportional
directly proportional
not dependent on each other

Explanation:

Colligative properties like freezing - point depression, boiling - point elevation, and osmotic pressure can be used to find the molar mass of a solute. The osmotic pressure formula is $\Pi = MRT$ (where $\Pi$ is osmotic pressure, $M$ is molarity, $R$ is the gas constant, and $T$ is temperature). When $\Pi$ is constant, $M$ and $T$ are inversely proportional ($M=\frac{\Pi}{RT}$).

Answer:

1. True
2. inversely proportional
