Question

A patient is given a solution containing 0.625 g of calcium carbonate. If the calcium carbonate solution contains 1250 mg per 5 mL, how many milliliters of the solution were given to the patient?

Answer 1

Answer: 2.5 mL

Explanation:

Given : A patient is given a solution containing 0.625 g of calcium carbonate.

i.e. Patient required calcium carbonate = 625 mg [∵ 1 g = 1000 mg]

Let x be the amount of solution ( in millimeters) given to the patients.

Ratio of amount of calcium carbonate (mg) to amount of solution (ml) =
`(625)/(x)`

If the calcium carbonate solution contains 1250 mg per 5 mL,

Then, Ratio of amount of calcium carbonate to amount of solution =
`(1250)/(5)`

By using proportion we have :-

`(625)/(x)=(1250)/(5)\\\\\Rightarropw\ x=(5*625)/(1250)=2.5`

Hence, 2.5 mL solution were given to the patient.
