Averapamil suspension is made from six tablets of 120 mg each. the recipe calls for each to be crushed and mixed with a small amount of water, the qs to a final volume of 60 mls. what is the final concentration?

Concentration of solution is defined as mass of solute in the given volume of solution.

The mass of 1 tablet is 120 mg thus, mass of same 6 tablets will be:

m=120×6=720 mg.

It is crushed and small amount of water is added to it to form a suspension. The final volume formed is 60 mL, concentration can be calculated using the following formula:

Here, C is concentration of solution, m is mass of tablets and V is volume of solution. On putting the values,

Therefore, final concentration will be 12 mg/mL.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
