Pragya tested the solubility of three different substances at different temperatures and collected the data as given below. Result are given in the following table, as grams of substances dissolved in 100 grams of water to form a saturated solution.a. Potassium nitrate would be needed to produce a saturated solution of potassium nitrate 50 grams of water at 313 K ?b. Pragya makes a saturated solution of potassium chloride in water at 353 K and leaves the solution to cool at room temperature. What would she observe as the solution cools ?c. Find the solubility of each salt at 293 K. Which salt has the highest solubility at this temperature?d. What is the effect of change of temperature on the solubility of a salt ? |
|
Answer» Answer: Solution verified Verified by Toppr (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.

What is the mass of the ethyl alcohol that exactly fills a 300.0 mL container? The density of ethyl alcohol is 0.889 g/mL. |
|
Answer» Answer: - Density will have UNITS of g m L when dealing with a liquid or units of g c m 3 when dealing with a solid. The mass has units of GRAMS, g . The volume will have units of m L or c m 3
We are given the density and volume, both of which have good units so all we have to do is REARRANGE the EQUATION to solve for the mass: d e n s i t y × v o l u m e = m a s s volume × volume
Density

What is the density of a sphere that has a radius of 6 cm and a mass of 100 g |
|
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 . |
