Sodium phosphate and calcium chloride react to form sodium chloride and calcium phosphate. If you have 379.4 grams of calcium chloride and an excess of sodium phosphate, how much calcium phosphate can you make?

Respuesta :

Answer:- 353.3 g

Solution:- The balanced equation is:

[tex]2Na_3PO_4+3CaCl_2\rightarrow 6NaCl+Ca_3(PO_4)_2[/tex]

We start with given grams of calcium chloride and convert them to moles. Then using mol ratio, the moles of calcium phosphate are calculated and converted to grams as.

Molar mass of calcium chloride is 110.98 gram per mol and molar mass of calcium phosphate is 310 gram per mol.

The set is made using dimensional analysis as:

[tex]379.4gCaCl_2(\frac{1molCaCl_2}{110.98gCaCl_2})(\frac{1molCa_3(PO_4)_2}{3molCaCl_2})(\frac{310gCa_3(PO_4)_2}{1molCa_3(PO_4)_2})[/tex]

= [tex]353.3gCa_3(PO_4)_2[/tex]

So, 353.3 grams of calcium phosphate can be formed.
