ASAP SHOW WORK FOR ALL what is the molarity of a solution that contains 1.56 moles of MgBr2 in 3.67 L of solution

What volume L of a 2.56 M solution would contain 2.456 Grams of Mg3(PO4)2

how many freaks of Cr2O3 are dissolved in 987 grams of water in 0.478 m of solution of Cr2O3

how many kilograms of solvent would contain 189 grams of NiBr2 if the solution was 1.62m

Option (A) is the correct answer.

Explanation:

When solute dissolved faster in one beaker then it means the rate of dissolution is faster as no other substance except the solute is present in the solution.

Whereas, in another beaker solute dissolved slowly therefore, rate of dissolution of solute is slow as it might be possible that some other substances including the solute are present in the solvent.

As a result, rate of dissolution has decreased into the water (solvent).

Since it is given that temperature was same in both the beakers. Thus, there is possibility that one of the beaker already had some solute.

Hence, we can conclude that the beaker that dissolved the solute slower already has some solute in it.
