Description : a) 110 g of salt is present in 550g of solution. Calculate the concentration of solution. b) 10 ml of H2SO 4 is dissolved in 90 ml of H2O. Calculate the concentration of solution. -Chemistry
Last Answer : The concentration of salt is determined by the division of mass of the solute by the mass of the solution and the percentage is obtained by multiplying the value by 100. The quotient of the division of 110 by 550 is 0.2 here. So after multiplying it with 100, it is 20%. So the concentration is 20%.
Description : The concentration of a salt solution in terms of mass by mass percentage is 20 and the mass of the solution is 550 g. Determine the mass of solute present in the solution. -Chemistry
Last Answer : Mass by mass percentage = 20% Mass of solution= 550gram Mass of solute/mass of solution multipled by 100 Therefore, 20/100 = 1/5 Hence, Mass of solute=Mass of solution/5 = 550gram/5 = 110Gram Therefore, The mass of solute is 110gm
Description : What is the percent by mass concentration of a solution that contains 5.30 of salt?
Last Answer : The concentration of a solution is basically how strong the solution is.
Description : After dissolving 0.25 kg of salt in 1 kg of water, its volume becomes 1200 cc. What is the concentration of solution ?
Last Answer : We know , 1 cc = 1cm ^ 3 = (10 ^ -6) m ^ 3 Density of salt water = (1 + 0.25) / (1200 × 10 ^ - ৬) = 1.04 kg / (m 3)

Last Answer : Ans:(d)
Description : Hypoglycemia refers to – (1) high salt concentration in blood (2) high blood sugar level (3) high blood pressure (4) low sugar level in blood
Last Answer : (4) low sugar level in blood Explanation: Hypoglycemia is an abnormally diminished content of glucose in the blood. The term literally means "low sugar blood". It can produce a variety of ... problems arise from an inadequate supply of glucose to the brain, resulting in impairment of function.
Description : Denaturation of a protein is caused by – (1) Heat (2) Acid (3) High salt concentration (4) All of the above
Last Answer : (4) All of the above Explanation: Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures.
