Question5 of 20if 2.891 g mgcl2 is dissolved in enough water to make 500.0 ml of solution, what is the molarity of the magnesium chloride solution? the molecular mass of magnesium chloride is 95.3 g/mol and the density of the solution is 1.22 g/ml.1.518 x 10-2 m5.782 x 10-3 m6.073 x 10-2 m0.5505 m5.782 m

Explanation:

Hello,

In this case, the molarity is defined as the ratio between the moles of the solute and the volume of the solution in liters:

Thus, the moles of the solute which is magnesium chloride are:

Nonetheless, the volume of the solution should be computed by adding the mass of both calcium chloride and water as we know the density of the solution as shown below:

Hence, the volume is:

Finally, the molarity results:

Best regards.

the answer is na (sodium)

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
