What is the mass percent of a solution formed by dissolving 50 g of glucose in 1000 g of water?
The total mass of the solution is the sum of the mass of the solute (glucose) and the mass of the solvent (water), which is 50 g + 1000 g = 1050 g. The mass percent of the solute (glucose) in the solution is the mass of the solute divided by the total mass of the solution, multiplied by 100. Therefore, the mass percent of glucose in the solution is (50 g / 1050 g) x 100 = 4.76%.
What is the mass percent of a solution that is prepared by dissolving 4.0 g of KCl in 50.0 g of H2O?
Mass percent is the ratio of the mass of solute to the total mass of solution expressed as a percent Here we have 4.0 g solute and total mass of solution of 4.0 g + 50.0 g = 54.0 g. So, the mass percent of KCl = 4.0 g/54.0g (x100) = 7.41% (3 sig figs)
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
What is the mass in grams of 0.330mol of calcium?
To find the mass in grams of 0.330 mol of calcium, you need to use the molar mass of calcium which is 40.08 g/mol. Mass = moles x molar mass Mass = 0.330 mol x 40.08 g/mol = 13.24 g.
How do you calculate percent by mass?
Example:- 454 g of orange jam contain 83 g sugar454 g jam---------------83 g sugar100 g jam----------------x g sugarx= 100x83/454= 18,18 g sugar (or 18 % sugar)
What is the least number that should be subtracted from 18448 to make it exactly divisible by 48?
It is: 16 because 18448-16 = 18432 and 18432/48 = 384

What is an initial mass of 48.702 g after heating the mass had decreased to 3.0662 g?
The initial mass is 48,702 g.
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)

An empty beaker has a mass of 115 g After some water is added to the beaker the mass is 147 g What is the mass of the water?
32 g
A student estimated the mass of a sample of powdered sulfur to be 35 g The actual mass of the sample was 42.5 g What was the error in this measurement?
The error in the measurement was 7.5 g. This was calculated by subtracting the estimated mass (35 g) from the actual mass (42.5 g).
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%
What is the mass of oxygen in 5.2 g of potassium nitrate?
This mass is 2,469 g.
What is the mass of oxygen in 250 g of sulfuric acid H2SO4?
To find the mass of oxygen in sulfuric acid (H2SO4), we first need to calculate the molar mass of the compound. The molar mass of H2SO4 is 98.08 g/mol. The molar mass of oxygen in H2SO4 is 4 * 16 = 64 g/mol. To find the mass of oxygen in 250 g of H2SO4, we can use the proportion: (64 g / 98.08 g) * 250 g = 161.3 g of oxygen.
