3 0

Answer:

The correct answer is option (a).

Explanation:

The very first postulate of kinetic gas theory discuss that the gases have a random motion of particles. The motion of the gas particles continues in a straight lines until or unless they get collide with another particles or with the walls of the containers.

Whereas as other postulates were:

  • Gas particles are of point masses with no volume.
  • No molecular forces are at work.
  • Gas pressure is due to collision of particles with walls of container.
  • Kinetic energy of the gas particles is measured in Kelvin temperature.
  • Lighter particles moves with higher speed than heavier gas particles.

When 20 milliliters of 1.0m hcl is diluted to a total volume of 60 milliliters, the concentration of the resulting solution is?
Ksenya-84 [330]
In preparing diluted solutions from concentrated solutions we can use the following formula
c1v1 = c2v2
c1 and v1 are the concentration and volume of the concentrated solution respectively
c2 and v2 are the concentrations and volume of the diluted solution respectively
Substituting these values ,
20 mL x 1.0 M = C x 60 mL
C = 0.33 M
The concentration of the resulting diluted solutions is 0.33 M

Convert 7.50 mol of Li₂O to grams
Natali5045456 [20]

Answer:

223.5 g

Explanation:

The formula between the number of moles, mass and Mr can be used to convert moles to grams.

<em>Number of moles = mass ÷ Mr</em>

So, mass = number of moles × Mr

  Mr of Li₂O = (6.9 × 2) + 16 = 29.8

∴ Mass = 7.5 × 29.8 = <u>223.5 g</u>
