55.83 grams is the mass of Calcium Phosphate will be formed according to the reaction when 75.2 grams of Calcium Sulfate are reacted with an unlimited amount of Sodium Phosphate.

Explanation:

Data given:

mass of calcium sulphate reacted= 75.2 grams

atomic mass of calcium sulphate = 136.14 grams/mole

balanced chemical reaction equation:

3CaSO_{4} +2 Na_{3} (PO_{4})_{2}   ⇒  Ca_{3} (PO_{4})_{2} + 3Na_{2}SO_{4}

number of moles of calcium phosphate given will be calculated as:

number of moles = \frac{mass}{atomic mass of 1 mole}

        putting the values in the above formula, we get

number of moles = \frac{75.2}{136.4}

                             = 0.55 moles of CaSO_{4} is given

From the balanced equation:

3 moles of CaSO_{4} reacts to give 1 mole of calcium phosphate

so, 0.55 moles of CaSO_{4} will react to form x moles of calcium phosphate

\frac{1}{3} = \frac{x}{0.55}

3x = 0.55

x = 0.18 moles of calcium phosphate is formed

mass = number of moles x atomic mass of calcium phosphate

(atomic mass of Ca_{3}(PO_{4}){3} =310.18 grams/mole)

putting the values in the formula:

mass = 0.18 x 310.18

          = 55.83 grams of calcium phosphate is formed.

How do you decide whether an observed property of matter is a physical or a chemical property?
Otrada [13]
By the object's composition and the acting agent to which factors the change of the substance or entity.
<span>The effect of physical property of matter on the object or substance can be better identified when the object doesn't change in composition or in nature. Unlike chemical property which has changed in its composition and atomic structure that was caused by chemical change or reaction due to an agent. Physical property is identified thru physical reactions or changes that has never changed the object in an atomic level, like cutting paper into smaller sizes. The aforementioned example illustrates physical proerty but being cut into smaller buts without changing the object from paper to any other substance, thus, its structure remain and its still called paper regardless of size, mass and texture. <span>

I need part 1 and 2 please , just separate answers
Vladimir79 [104]

First, we have to remember the molarity formula:

M=\text{ }\frac{moles\text{ of solute}}{L\text{ solution}}

Part 1:

In this case, our solute is sodium nitrate (NaNO3), and we have the mass dissolved in water, then we have to convert grams to moles. For that, we need the molecular weight:

M.W_{NaNO_3}=\text{ 23+14+16*3= 85 g/mol}

Then, we calculate the moles present in the solution:

3.976\text{ g NaNO}_3\text{ * }\frac{1\text{ mol}}{85\text{ g}}=\text{ 0.04678 mol NaNO}_3

Now, we have the necessary data to calculate the molarity (with the solution volume of 200 mL):

M=\frac{0.04678\text{ mol}}{200\text{ mL*}\frac{1\text{ L}}{1000\text{ mL}}}=\text{ 0.2339 M}

The molarity of this solution equals 0.2339 M.

Part 2:

In this case, we have the same amount (in moles and mass) of sodium nitrate, but a different volume of solution, then we only have to change it:

M=\text{ }\frac{0.04678\text{ mol}}{275\text{ mL *}\frac{1\text{ L}}{1000\text{ mL}}}=\text{ 0.1701 M}

So, the molarity of this solution is 0.1701 M.
