How many moles of strontium chloride are included in 20 ml of 0.2 m strontium
chloride?

Number of moles of strontium chloride = 0.004 mol

Explanation:

Given data:

Molarity = 0.2 M

Volume = 20 mL

Moles of strontium chloride = ?

Solution;

Formula:

Molarity = number of moles of solute / volume in litter

Now we will convert the volume into litter.

20 mL/1000mL × 1 L

0.02 L

Now we will put the values in formula:

Molarity = number of moles of solute / volume in litter

Number of moles of solute = Molarity × volume in litter

Number of moles of solute = 0.2 mol/L × 0.02 L

Number of moles of solute = 0.004 mol

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
