Apatient 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?

2.5 mL

Step-by-step 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) =

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

Then, Ratio of amount of calcium carbonate to amount of solution =

By using proportion we have :-

Hence, 2.5 mL solution were given to the patient.

the answer

b. they are parallel and will never intersect.
