Sodium phosphate and calcium chloride react to form sodium chloride and calcium phosphate. If you have 379.4 grams of calcium ch
GalinKa [24]

Answer:- A. 353.5 g

Solution:- The balanced equation is:

2Na_3PO_4(aq)+3CaCl_2(aq)\rightarrow 6NaCl(aq)+Ca_3(PO_4)_2(s)

From this equation, there is 3:1 mol ratio between calcium chloride and calcium phosphate.

Grams of calcium chloride are converted to moles and these moles are multiplied by the mol ratio to get the moles of calcium phosphate. Finally the moles are multiplied by molar mass to get the grams of calcium phosphate.

Molar mass of CaCl_2 = 40.078+2(35.45) = 110.978 g per mol

Molar mass of Ca_3(PO_4)_2 = 3(40.078)+2(30.974)+8(16.00)

= 120.234+61.948+128.00 = 310.182 g per mol

let's make the set up using dimensional analysis.

379.4gCaCl_2(\frac{1molCaCl_2}{110.978gCaCl_2})(\frac{1molCa_3(PO_4)_2}{3molCaCl_2})(\frac{310.182gCa_3(PO_4)_2}{1molCa_3(PO_4)_2})

= 353.5gCa_3(PO_4)_2

Hence, 353.5 g of calcium phosphate will form and so the correct option is A.

DochEvi [55]

Answer:

Number of moles = 1.57 mol

Explanation:

Given data:

Mass of propanol = 94.1 g

Molar mass of propanol = 60.1 g/mol

Number of moles of propanol = ?

Solution:

Formula:

Number of moles = mass/molar mass

by putting values,

Number of moles = 94.1 g/ 60.1 g/mol

Number of moles = 1.57 mol
