**how do you find a number of moles when the mass is given**

13/10/2008 · You can't convert just density into moles. Density is an intensive property, number of moles is an extensive property, they are not related. However, you are given extensive property - …... To find out the mass of this compound, first find the molar mass of each element that makes up the compound by referring to the periodic table. To do the actual calculation of the compound, each element's molar mass is multiplied by the number of moles of …

**How to Mole mole Day**

the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is ; represented by subscripts in the empirical formula. If the number is too far to round (x.1 ~ x.9), …... We know from the information given that we have an equal mass of each compound, but no real numbers to plug in and find moles. So what can we do? Since we have an equal mass of each compound, if we calculate the percent by mass of oxygen in each compound, we could just compare their ratios, since we know that the mass is directly related to number of moles (which is directly …

**Given Moles Convert to Grams ChemTeam**

The molar mass of NaCl is 58.44 which means we also have 1 mole of NaCl. Since two moles of NaCl are required to react with 1 mole of sulphuric acid to produce 2 moles of HCl, then we only have enough NaCl to produce an equivalent molar amount of HCl. how to find same files on computer Letting N be the number of molecules or moles of the substance, the formula to convert from molecules to grams is then given as (N number of molecules) /(6.022 x 10^23) x (substance's molar mass in grams/mol).

17/05/2009 · Best Answer: you were given moles = 0.117 mole molar mass = 34 g/mole so mass = 0.117 moles x (34 g / 1mole) = 4.0 g H2O2.. ***** where the 25 mL comes into play is this.. IF you were asked to find molarity.. 0.117 moles / 0.025 L = 4.7 M IF you were given density.. like say density = 1.06 g / mL and asked how to find patents by company To find the number of atoms in a sample, divide the weight in grams by the amu atomic mass, then multiply the result by 6.02 x 10^23. To find the number of atoms in a sample, divide the weight in grams by the amu

## How To Find Number Of Moles Given Mass

Calculate the number of moles in the following mass: 12.34 gAu Given: 12.34 g Au Need: Moles Unknown: Au atomic mass= 196.967g Au 1 mol

- 19/10/2008 · After finding the mass of your hydrocarbon would divide the mass of the sample by the mass for one mole which in your case is 0.0559 moles. After this to find the molecules in the sample you need to know Alvarado’s number which is 6.02x10^23 molecules per mole so multiple this by the amount of moles (0.0559). Then from the amount of molecules there are 12 atoms in C6H6.
- We know from the information given that we have an equal mass of each compound, but no real numbers to plug in and find moles. So what can we do? Since we have an equal mass of each compound, if we calculate the percent by mass of oxygen in each compound, we could just compare their ratios, since we know that the mass is directly related to number of moles (which is directly …
- You can use the technique given here to find the answer to your particular problem. First you need to find the molecular weight of the compound. Once you've done that, then you simply divide the mass of the compound (in grams) by the molecular weight of the compound (in amu). The result is the number of moles. For example: Water (H2O) has a molecular weight of 2 * 1.0 (for the two hydrogens, 1
- Letting N be the number of molecules or moles of the substance, the formula to convert from molecules to grams is then given as (N number of molecules) /(6.022 x 10^23) x (substance's molar mass in grams/mol).
