Answer:

If it is tested in a controlled setting with repeated results.

Explanation:

Hello,

Every scientific foundation is preceded by a series of repetitive tests which allow the scientists to state both reliable and trustful conclusions. In such a way, by repeating the aforesaid test, the conclusion is strengthened, nevertheless, those tests must be carried out in a controlled manner in order to assure that the proposed conclusion is suitable under the specified conditions for scientific claims.

Best regards.

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.
