Amount of F atoms = (1.50x1023)/(6.02x1023) = 0.249mol
Note: F in elemental form exists as diatomic F2 so the amount of fluorine gas would be 0.125mol.

How many moles of (NH4)2S are there in 150 g of (NH4)2S?
150 g x 1 mol/68.154 g = 2.2 moles (2 sig figs)
How many moles are in 150 grams what compound NaCl?
Divide by molar mass of NaCl (not NaCI ! ) which is 58.44 g/mol NaCl.
What mass of calcium bromide is needed to prepare 150.0 mL of a 3.50 M solution?
3.5M / 1000, x 150 = how many moles you need. = .525 moles. moles = mass / molec mass. molec mass if cabr2 is 199.86 g/mol. .525 x 199.86 is 104.93g CaBr2
What is the final concentration if 100 mL of water is added to 25.0 mL of 6.0 M NaCl?
We must first figure out the amount of NaCl in moles: M = mol/L = mmol/mL 6 = mmol/25 mL 150 mmol NaCl Now divide by the total volume to get the final concentration: 150 mmol/100 mL = 1.5 M NaCl
How many moles of copper are present in 75.92 g?
The atomic mass of Copper is 63.5 grams One mole of any element has a mass equal to the atomic mass. 0.75 grams of Cu = x moles of Cu 63.5 grams of Cu = 1 mole of Cu Set up a proportion and solve for x Divide 0.75 / 63.5 = x /1 0.75 ÷ 63.5 = x
How many atoms are present in 23.0 mol of Ti?
1 mol = 6,022 x 10^23 molecules of HI. So: 6,022E23 *0,3 = Your answer !
How deep can moles dig?
150
How many moles of atoms are in 150 g sulfur?
The reaction equation is 2 NaHCO3 + H2SO4 = 2 CO2 + 2H2O + Na2SO4. This means that for every mole of sulfuric acid, two moles of NaHCO3 are needed. 150 grams of H2SO4 is 1.53 moles, so 3.06 moles of NaHCO3 are required.
If 20.0 mL of 150 M NaOH are used in a titration how many moles of NaOH are used?
150 M NaOH = 150 mole / liter 20.0 mL = 0.0200 L 150 * 0.0200 = 3 moles
How many moles of (NH4)2S are there in 150 g of (NH4)2S?
150 g x 1 mol/68.154 g = 2.2 moles (2 sig figs)
How many moles of sulfuric acid are present in 0.550 L of a 0.150 M sulfuric acid solution?
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
Is .15 and .150 the same amount?
Is .15 and .150 the same amount? *********************************** Yes.
What mass of NaHCO3 is needed to neutralize 150ml of 044M HCl?
Several part problem. Get molarity of NaHCO3. (150 ml)( M NaHCO3) = (150 ml)(0.44 M HCl) = 0.44 M NaHCO3 --------------------------- get moles NaHCO3 ( 150 ml = 0.150 Liters ) 0.44 M NaHCO3 = moles NaHCO3/0.150 Liters = 0.066 moles NaHCO3 ---------------------------------------get grams 0.066 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 5.54 grams NaHCO3 needed ---------------------------------------------answer
How many moles are there in 150 grams of Al(OH)3?
The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol150 g x 1 mol/78 g = 1.92 moles
How many moles of ammonium sulfate are in 150g sample?
150/132 equals 1.136moles
300 percent of what amount of money is 150?
50 because 50 * 300%, or 3.0, is 150
What is yardstick of atoms?
The atomic radius is approx. 150 pm and is different for each element.
