1826.5g of methanol (CH3OH), molar mass = 32.0 g/mol is added to 735 g of water, what is the molality of the methane 0.0348 m 1.
Snowcat [4.5K]

Answer:

Molality = 1.13 m

Explanation:

Molality is defined as the moles of the solute present in 1 kilogram of the solvent.

Given that:

Mass of CH_3OH = 26.5 g

Molar mass of CH_3OH = 32.04 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{26.5\ g}{32.04\ g/mol}

Moles\ of\ CH_3OH= 0.8271\ moles

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )

So, molality is:

m=\frac {0.8271\ moles}{0.735\ kg}

<u>Molality = 1.13 m</u>

which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory
sertanlavr [38]

C.  two billiard balls colliding and bouncing off each other

Explanation:

From the given options, the most similar scenario to the type of collision depicted in the kinetic molecular theory is the collision of the two billiard balls bouncing off each other.

Here are some of the postulates of the kinetic molecular theory:

  • A gas is composed of a large number of identical molecules moving at different speeds.
  • The space occupied by the gas molecules is negligible compared to the volume of the container.
  • Molecules move independently of one another
  • Molecules collides  with one another and with the walls of the container elastically i.e without loss of kinetic energy.
  • The temperature of the gas is a measure of its average kinetic energy.
