I assume you mean ml of water. 1ml of water=1gm of water. So you have 25.5gm divided by 425 gm to get the proportion. Multiply this by 100 to get the precent. I feel like I'm answering your homework for if I go on but.....the equation is like this
25.5g / 425g = 0.06 (no units because you divided grams by grams so the grams cancel out)
Then,
0.06 * 100% = 6% (now there are units because you multiplied a no-unit by a
percent)

To calculate the percent by mass of a solution, you need to know the total mass of the solution. In this case, additional information about the density of the solution is required to determine the total mass. Once you have the total mass, divide the mass of NaCl by the total mass and multiply by 100 to find the percent by mass.

What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?
To find the concentration in mass percent, first calculate the total mass of the solution (50.0g NaCl + 150.0g water = 200.0g total). Then, divide the mass of NaCl by the total mass of the solution and multiply by 100 to get the concentration in mass percent: (50.0g NaCl / 200.0g total) * 100 = 25.0% NaCl.
What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
The mass of the solution is the sum of the mass of NaCl and the mass of water. First, we calculate the mass of the solution by multiplying the density by the volume: 1.08 g/mL * 1100 mL = 1188 g. The mass percent of NaCl in the solution is then found by taking (mass of NaCl / mass of the solution) * 100%: (138 g / 1188 g) * 100% = 11.62%.
Does the Mass mass percent concentration measures grams of solute per grams of solvent?
No, the mass percent concentration is a ratio of the mass of the solute to the total mass of the solution, expressed as a percentage. It is calculated by dividing the mass of the solute by the mass of the solution (solute + solvent) and multiplying by 100.
What is the percent of mass of 4.35 gm of NaCl dissolved in 105.0 gm of water.?
Total mass = 4.35 g + 105.0 g = 109.35 g% by mass of NaCl = 4.35/109.35 (x100%) = 3.98% (3 significant figures)
A 20.0-g sample of sugar is dissolved in 59.8 g of water. What is the concentration of the solution?
25 percent by mass
What is the percent by mass of NaCl in a solution containing 20g of NaCl dissolved in 600g of H2O?
9%
What mass of water must be added to 255.0g NaCl to make a 15.00 percent by mass aqueous solution?
To make a 15.00% by mass aqueous solution with NaCl, the mass of NaCl is 255.0g. This means that 15.00g of NaCl is present in every 100.00g of solution. To find the mass of water needed, first calculate the mass of NaCl in the final solution, then subtract this amount from the total mass of the solution (water + NaCl).
What is the mass percent of NaCl when 6.5g of NaCl dissolves with 250g of water?
This concentration of NaCl is 2,6 g NaCl/100 mL solution.
What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?
To find the concentration in mass percent, first calculate the total mass of the solution (50.0g NaCl + 150.0g water = 200.0g total). Then, divide the mass of NaCl by the total mass of the solution and multiply by 100 to get the concentration in mass percent: (50.0g NaCl / 200.0g total) * 100 = 25.0% NaCl.
How do you calculate the percent by mass of 4.35g of NaCl dissolved in 105 g of water?
% by mass is the mass of the solute divide by the total mass of solution times 100%. Or put another way, % by mass = mass solute/total mass of soln (x100%).Mass solute = 4.35 gMass of solution = 4.35 g + 105 g = 109.35 g (assuming a density of 1g/ml for water)% NaCl by mass = 4.35 g/109.35 g (x100%) = 3.98 % (to 3 significant figures)
How do you calculate for the mole of a solution?
number of moles is mass divided by molecular mass. the molecular mass of NaCl is 58.44g/mol. therefore you need 58.44g to make one mole
What is the mass percent of the solution. if An aqueous NaCl solution is made using 138 g of NaCl diluted to a total solution volume of 1.10 L Assume a density of 1.08 g per ml for the solution.?
The mass of the solution is the sum of the mass of NaCl and the mass of water. First, we calculate the mass of the solution by multiplying the density by the volume: 1.08 g/mL * 1100 mL = 1188 g.

What mass of NaCl is needed to make 414 g of a 3.06 percent NaCl solution?
If your solution is a total of 414g and 3.06% of it needs to be NaCl, then you just take 414 x .0306 = grams of NaCl. The rest of the grams will be from other species in the solution.
What is the percent by mass of the solute sodium hypochlorite is 5.24 percent you have a 2500.0 grams of bleach solution. How many grams of NaCl are in the solution?
If the percent by mass of sodium hypochlorite (NaClO) in the bleach solution is 5.24%, then 100% - 5.24% = 94.76% is the water weight. For a 2500.0g solution, the mass of NaClO is 5.24% of 2500g = 131g. Since the remaining mass is water, the mass of NaCl (sodium chloride) in the solution would be zero.
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%.
Does the Mass mass percent concentration measures grams of solute per grams of solvent?
No, the mass percent concentration is a ratio of the mass of the solute to the total mass of the solution, expressed as a percentage. It is calculated by dividing the mass of the solute by the mass of the solution (solute + solvent) and multiplying by 100.
What is the mass percent of sodium chloride in a solution prepared by adding 1 g of sodium chloride to 50 g of water?
The mass percent of sodium chloride can be calculated as follows: Mass of NaCl = 1 g Mass of water = 50 g Total mass of solution = 1 g + 50 g = 51 g Mass percent of NaCl = (Mass of NaCl / Total mass of solution) x 100% = (1 g / 51 g) x 100% ≈ 1.96%
