What is the percent of a solution containing 2.19 g NaCl in 75 g of the solution?

The percent of a solution is calculated by dividing the mass of the solute by the total mass of the solution, then multiplying by 100. In this case, the percent of the solution containing 2.19 g of NaCl in 75 g of the solution would be (2.19 g / 75 g) * 100 = 2.92%.


What is the percent by volume of 25 ml of methanol in 75 ml of water?

With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.


If a 25 g sample of sugar was dissolved in 50 g of water The concentration of the solution is?

To determine the concentration of the solution, we need to calculate the total mass of the solution first. The total mass is the sum of the mass of sugar (25 g) and the mass of water (50 g), which equals 75 g. The concentration of the solution is then calculated by dividing the mass of the solute (sugar) by the total mass of the solution: (25 g / 75 g) x 100% = 33.33%. Therefore, the concentration of the solution is 33.33%.


What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?

(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.


What number is 75 percent of 100?

75% of 100 = 75% * 100 = 0.75 * 100 = 75


The solubility of kno3 is 155g per 100g of water at 75 degree c and 38g at 25degreec the mass of kno3 will crystallize out of solution if 100g of it saturated solution is cooled from 75c to 25 c is?

The mass of KNO3 that will crystallize out of solution can be calculated by finding the difference between the solubility limit at 75°C and the amount dissolved at 25°C. At 75°C: 100g solution contains 155g KNO3 At 25°C: 100g solution contains 38g KNO3 The amount that will crystallize out = 155g - 38g = 117g

Will 110 g of KNO3 in 100 g of water at 40 degrees Celsius be saturated or unsaturated?

At 40 degrees Celsius, 110 g of KNO3 is more than the solubility limit of KNO3 in 100 g of water. Therefore, the solution will be saturated because it has dissolved the maximum amount of KNO3 that it can hold at that temperature.
