What is the concentration of Na2SO4 solution prepared by dissolving 5.35 g of Na2SO4 in sufficient water to give 330 ml of solution?
First.Get moles sodium sulfate.5.35 grams Na2SO4 (1 mole Na2SO4/142.05 grams)= 0.0377 moles Na2SO4-------------------------------------Second.Molarity = moles of solute/Liters of solution ( 330 mL = 0.33 Liters )Molarity = 0.0377 moles Na2SO4/0.33 Liters= 0.114 M Na2SO4=============
When 125 grams of solution was evaporated to dryness. 14.3 grams of solute was recovered what was the percentage of the solute?
The percentage of solute in the solution is calculated by dividing the mass of the solute recovered (14.3g) by the initial mass of the solution (125g) and then multiplying by 100. Percentage of solute = (14.3g / 125g) * 100 = 11.44%, or approximately 11.4%.
What is the percentage by mass of salt solution prepared by dissolving 11 grams of salt in 80 grams of solution with solution?
The percent concentration is 13,75 %.
What is the mass percent of a solution prepared by dissolving 18.9 grams of solid into 39.5 grams of water?
32.4
What percentage is a solution that contains 9 grams of sodium chloride?
That depends on how much solvent you are dissolving the 9 grams of salt in.
What is the percentage concentration of a solution prepared by dissolving 5.48 grams of silver nitrate in 25.0 grams of water?
The percentage concentration of the solution can be calculated as (mass of solute / total mass of solution) x 100. In this case, the mass of the solute (AgNO3) is 5.48 grams and the total mass of the solution is 5.48 grams (AgNO3) + 25.0 grams (water) = 30.48 grams. Therefore, the percentage concentration is (5.48 / 30.48) x 100 ≈ 17.98%.
What is the molar mass of haemocyanin and the freezing point of the solution when an aqueous solution is prepared by dissolving 1.5 grams of haemocyanin a protein obtained from crabs in 0.25 litres of?
Haemocyanins are a group of proteins.
What is the molarity of a solution made by dissolving 25 grams of Mg in excess NaOH solution?
The molarity of the solution is 0.5 M.
What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
What is the formula of mass percentage?
grams solute ------------------ x 100 grams solution
If the percentage for a solute is 4 per cent and the mass of the solution is 200 grams what is the mass of the solute in solution?
200 grams of solution will contain 200 x 4% or 200 x 0.04 = 8.0 total grams of solute.

Calculate the dissolving rate for 5.0 grams of rock salt to enter solution if it took 200 seconds.?
To find the dissolving rate, you divide the time by the mass. --> 200s/5grams=40mL/s
