Calculate the mass of calcium phosphate and the mass of sodium chloride that could be formed when a solution containing 12.00g of sodium phosphate is added to a solution containing 10.0g of calcium chloride

Answer : The mass of calcium phosphate and the mass of sodium chloride that formed could be, 9.3 and 10.5 grams respectively.

Explanation : Given,

Mass of = 12.00 g

Mass of = 10.0 g

Molar mass of = 164 g/mol

Molar mass of = 111 g/mol

Molar mass of = 58.5 g/mol

Molar mass of = 310 g/mol

First we have to calculate the moles of and .

and,

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is:

From the balanced reaction we conclude that

As, 3 mole of react with 2 mole of

So, 0.0901 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of  and

From the reaction, we conclude that

As, 3 mole of react to give 6 mole of

So, 0.0901 mole of react to give mole of

and,

As, 3 mole of react to give 1 mole of

So, 0.0901 mole of react to give mole of

Now we have to calculate the mass of  and

and,

Therefore, the mass of calcium phosphate and the mass of sodium chloride that formed could be, 9.3 and 10.5 grams respectively.
