How many moles of water are there in 1.792 L?
95,474 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 moles of sodium borohydride are used in 100 mg?
.0104 mol
HOW MANY moles of mg atom are there in 100 gm of mg?
The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
How many moles of HCl are there in 230 cm cubed of 2M hydrocloric acid?
0.46 moles (230/100 x 2)
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 are there in 100.0 moles of Si?
100 times Avogadro's Number = 6.022 X 1025.
Is 100 aluminum atoms heavier than 100 led atoms?
No. 100 lead atoms are several times heavier than 100 aluminum atoms.
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
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
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
