Answer:

Mass = 46.52 g

Explanation:

Given data:

Mass of sodium phosphate react = 49.33 g

Mass of calcium phosphate produced = ?

Solution:

Chemical equation:

2Na₃PO₄ + 3Ca(NO₃)₂       →     Ca₃(PO₄)₂ + 6NaNO₃

Number of moles of Na₃PO₄:

Number of moles = mass/molar mass

Number of moles = 49.33 g/ 163.94 g/mol

Number of moles = 0.300 mol

now we will compare the moles of Na₃PO₄ and Ca₃(PO₄)₂

                Na₃PO₄         :             Ca₃(PO₄)₂

                    2                :               1

                 0.300           :             1/2×0.300 = 0.15

Mass of Ca₃(PO₄)₂:

Mass = number of moles × molar mass

Mass = 0.15 mol × 310.14 g/mol

Mass = 46.52 g

Using the gas laws, the volume of nitrogen produced is 6.6 L.

<h3>What is the product of a reaction?</h3>

We know that the product of a reaction is obtained from the balanced reaction equation. The reactants combine together to yield the products hence we have; N2 + 3H2 ----> 2NH3

We know that 1 mole of hydrogen occupies 22.4 L

x moles of hydrogen occupies 25500 L

x = 1 mole * 25500 L/ 22.4 L

x = 1138.4 moles

If 3 mole of hydrogen reacts with 1 mole of nitrogen

1138.4 moles  reacts with 1138.4 moles * 1 mole/ 3 moles = 379.5 moles

Mass of nitrogen = 379.5 moles * 28 g/mol = 10626 g

Now 3 moles of hydrogen produces 44.8 L of NH3

1138.4 moles  produces 1138.4 moles * 44.8 L/ 3 moles = 17000 L

Now;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2 = 1 * 17000 * 848/5.5 * 273

V2 =9601 L

2) 2NH4NNO3(s) ---> 4H2O(g) + 2N2(g) + O2(g)

Number of moles = 12g/ 80 g/mol = 0.15 moles

Now;

2 moles of NH4NNO3 produced 2 moles of nitrogen hence 0.15 moles of N2 was produced.

1 mole of N2 occupies 22.4 L

0.15 moles of N2 occupies 0.15 moles  *  22.4 L/1 mole = 3.36 L

P1 = 760 torr

V1 = 3.36 L

T1 = 273 K

P2 = 745 torr

T2 = 527 degrees or 800 K

V2 = ?

V2 =  P1V1T2/P2T1

V2 =  760 *  3.36 * 527/745 * 273

V2 = 6.6 L
