Chemistry
1 answer:
vivado [14]2 years ago
5 0

Answer:

1 km * 1000 m / km * 100 cm / m = 10^5 cm / km

V = 4 / 3 pi R^3

V = 4 / 3 * pi * (7.01 * 10^5 * 10^5)^3 = 4 / 3 pi * 344 * (10^10)^3

V = 1.443^10^3 * 10^30 = 1.44 10^33cm^3

a 1.642 g sample of calcium bromide is dissolved in enough water to give 469.1 mL of solution what is the bromide ion concentrat
aleksklad [387]

The bromide concentration in this solution of calcium bromide dissolved in enough water to give 469.1 mL is 1.75 × 10-⁵M.

<h3>How to calculate concentration?</h3>

The concentration of a solution can be calculated by dividing the number of moles of the substance by its volume.

No of moles of calcium bromide is calculated as follows:

moles = 1.642 ÷ 199.89 = 8.215 × 10-³moles

Molarity = 8.215 × 10-³moles ÷ 469.1mL = 1.75 × 10-⁵M

Therefore, the bromide concentration in this solution of calcium bromide dissolved in enough water to give 469.1 mL is 1.75 × 10-⁵M.
