Question

There is 43 μg of calcium in a total volume of 89 ml. The concentration of calcium is ___________.

a) 0.483 μg/ml
b) 0.966 μg/ml
c) 1.5 μg/ml
d) 2.05 μg/ml

Answer 1

The concentration of calcium in the solution is 0.483 µg/mL, which is calculated by dividing the amount of calcium (43 µg) by the total volume of the solution (89 mL).

Step-by-step explanation:

To calculate the concentration of calcium in the given solution, we use the formula for concentration, which is the amount of solute divided by the volume of solution:

Concentration (C) = amount of solute (mass) / volume of solution

Given that there is 43 µg of calcium in a total volume of 89 mL, we can calculate the concentration as follows:

Concentration (C) = 43 µg / 89 mL = 0.483 µg/mL

Therefore, the concentration of calcium in the solution is 0.483 µg/mL, which corresponds to option (a).
