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 A compound contains 14.5 g of magnesium and 3.5 g of oxygen. What is the mass percent of oxygen in the compound?
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.
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 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)
What is the mass in grams of 0.330mol of calcium?
The mass is 0.330 mol Ca (40.08 g/mol) = 13.2 g Ca
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)
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%.
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 of oxygen in 5.2 g of potassium nitrate?
This mass is 2,469 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%
