How many moles of phosphorus atoms are in 100 grams of P4S10?
4.00
How many moles of phosphorus atoms are in a 100 g sample of phosphorus?
The gram atomic mass of phosphorus is 30.9738, and by definition, a mole of such atoms contains Avogadro's Number of atoms. Therefore, 100 g of phosphorus contains 100/30.9738 or 3.23 moles, to the justified number of significant digits.
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
Which would lower the freezing point more 100 moles of sugar or 100 moles of NaCl?
100 moles of NaCl

How many atoms are there in 100.0 moles of Si?
100 times Avogadro's Number = 6.022 X 1025.
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
How many moles of water are there in 1.792 L?
95,474 moles
How many moles of Al2S3 are in 100 g of Al2S3?
100/150.158 is 0.666 moles
How many moles of carbon are present in a 100g sample?
moles = mass (g) divided by the molecular weight (g/mol) moles = 100g/12.01
How many molecules are in 2 moles of Cl?
For this problem you need the atomic masses of the elements to find the molecular mass (added atomic masses). Then take the atomic mass of Cl and divide it by the molecular mass (multiplied by 100) to get a percent. This will be the percent of Cl in all compounds of HCl. Then you can use this percent and apply it to the 2 moles.H- 1.00Cl- 35.5HCl- 36.535.5 / 36.5 × 100 = 97.3% Cl in HClSo we know that in 2 moles of HCl, 97.3% of it is Cl.97.3% of 2.00 moles HCl = 1.95 moles of Cl in 2 moles HClNow we have to find out how many atoms this is (convert moles to atoms). Take the number of moles and multiply it by Avogadro's constant, 6.02 × 1023.1.95 moles Cl × 6.02 × 1023 = 1.17 × 1024atoms of Cl in 2 moles of HCl
How many Zn atoms are in ZnClO3 2?
There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.
5.8 grams in 1 liter of water equals how many moles?
if you have 100 liters how many moles does that equal?
How many moles of sodium borohydride are used in 100 mg?
.0104 mol
Why does chlorine melt at -100 degrees but need 1000 degrees to split molecules to atoms?
Chlorine molecules (Cl2) have of strong covalent bonds between the two Cl atoms. The bonds between one MOLECULE and another however are much weaker.
