If you're question is referring to finding a percentage once you already have the mass, then all you do is multiply the mass by the percent. Since percent is always out of 100, you divide your percent by 100 to get a decimal form (for example 92% becomes .92). Since calculators don't usually allow for a percentage sign, you take your new-found decimal and multiply it by your mass. I hope this helps

What is the equation used to calculate percent by mass?
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
How to calculate the percent composition of F in NaF?
To find percent composition, you must work with the atomic masses. Look on a periodic chart to find the atomic masses of F and Na. You will find that Na has an atomic mass of 22.990 grams per mole of Na and that F has an atomic mass of 18.998 grams per mole of F. So, add these both together, and that will tell you how much mass NaF will be. NaF will have a mass of 41.988 grams per mole of NaF. Now to take the percent composition of F in NaF, simply divide the mass of F by the mass of NaF. That will give you [18.998/41.988]=.452 which will be about 45%. So your answer is that F has a 45% composition of NaF. PS: Since Na and F only had a stoichiometry of 1 (meaning there is 1 Na and 1 F in the molecule), no multiplication of the atomic masses was necessary when calculating the total mass of the molecule.
How do you convert mass fraction to weight percent?
Multiply the mass fraction by 100.

How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
How find percent compsotion of oxygen in Na2O?
To find the percent composition of oxygen in Na2O, first calculate the molar mass of Na2O (Sodium oxide) which is 61.98 g/mol. The molar mass of oxygen is 16 g/mol. Then, calculate the percent composition of oxygen in Na2O using the formula: (16 g/mol / 61.98 g/mol) * 100. This gives you the percent composition of oxygen in Na2O, which is approximately 25.8%.
What is the mass percent of hydrogen in ammonium phosphate NH4 3PO4?
To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.
What is the percent by mass of oxygen in propanal CH3CH2CHO?
To find the percent by mass of oxygen in propanal (CH3CH2CHO), calculate the molar mass of oxygen (O) and the molar mass of the entire compound. Then divide the molar mass of oxygen by the molar mass of the entire compound and multiply by 100 to get the percentage. In this case, the percent by mass of oxygen in propanal is around 47.3%.
What is the percent composition of calcium iodide?
Calcium iodide has the chemical formula CaI2. To find the percent composition, calculate the molar mass of CaI2, then find the molar mass contributed by each element (calcium and iodine). Finally, divide the molar mass contributed by each element by the total molar mass of CaI2 and multiply by 100 to get the percent composition.
What is the percent composition by mass of ca in caso4?
The molar mass of CaSO4 is 136.14 g/mol. The molar mass of Ca in CaSO4 is 40.08 g/mol. To find the percent composition of Ca by mass, divide the molar mass of Ca by the molar mass of CaSO4 and multiply by 100. This gives a percent composition of approximately 29.4%.
How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
What is the mass percent of chlorine in chloroform CHCl3?
To calculate the mass percent of chlorine in chloroform (CHCl3), you would first find the molar mass of the compound, which is 119.38 g/mol. Then, determine the molar mass of chlorine in the compound, which is 35.453 g/mol. Calculate the mass percent of chlorine by dividing the molar mass of chlorine by the molar mass of the compound and multiplying by 100. In this case, the mass percent of chlorine in chloroform is about 29.7%.
What is the percent of nitrogen in CN2H4O?
The molar mass of CN2H4O is 42 g/mol. The molar mass of nitrogen is 14 g/mol. To find the percent of nitrogen in CN2H4O, divide the molar mass of nitrogen by the molar mass of CN2H4O and multiply by 100. The percent of nitrogen in CN2H4O is approximately 33.3%.
A sugar solution of 35.8g sugar and 125.35g of water. what is the percent by mass of the sugar and the percent by mass of the water in the solution?
To find the percent by mass of sugar: Mass of sugar = 35.8g Total mass of solution = 35.8g (sugar) + 125.35g (water) = 161.15g Percent by mass of sugar = (mass of sugar / total mass of solution) * 100 To find the percent by mass of water: Mass of water = 125.35g Total mass of solution = 161.15g (as calculated above) Percent by mass of water = (mass of water / total mass of solution) * 100
Is mass percent the same as percent by mass?
Yes, mass percent and percent by mass are the same concept. Both terms refer to the percentage of a component in a mixture by mass.
