(a) At 313 K 62 g of potassium nitrate dissolved in 100 g of water. So to produce a saturated solution of potassium nitrate in 50 g of water we need

100

62

×50=31 g of potassium nitrate.

(b)Some SOLUBLE potassium CHLORIDE will separate out in the form of crystal at room TEMPERATURE because the solubility of potassium chloride will decrease.

(c)

(i) Solubility of Potassium nitrate at 293 K is 32 g.

(ii) Solubility of sodium chloride at 293 K is 36 g.

(iii) Solubility of Potassium chloride at 293 K is 35 g.

(iv) Solubility of Ammonium chloride at 293 K is 37 g.

The solubility of Ammonium chloride is highest at this temperature.

(d)The solubility of salt increases with the increase in temperature.

ANSWER:

The DEFINITION of density of a body is MASS of the body per unit volume of the body. From this we get Density = Mass/Volume.

In the above problem, We have 2 things: Mass of the sphere is 100 g and Radius of the sphere is 3 centimeter.

Thus we have to find the volume of the sphere.

The formula for finding the volume of a sphere is:

4/3*pi*R*r*r( Here r stands for radius..we find r to the power 3)

If u do math here, the vol. of the sphere is 113.1 cm 3 .

So we have the mass and volume of the sphere. That’s all that we need. Just plug in the values: Density= 100/113.1 g/cm 3 .

If you do the math here, you get the value of density of the sphere as 0.8841 g/cm 3 .
