The molar mass, that is mass per mole is given in the periodic table. The mass of one Cl-atom is approximately 35,45g/mole. In Cl2 there are 2, henbce you multiply the molar mass with 2.

How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
What is the molar mass of C6Cl6?
mass of 6 moles of C = 12X6 =72g mass of 6 moles of Cl = 35.5X6 = 213g mass of 1 mole of C6Cl6 = 285g
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 moles of Cl- ions are needed to completely combine with 0.25 moles of Mg plus 2ions?
0,5 moles Cl-
How many moles are in 1 g of Cl2?
# of Moles = Mass in grams divided by Molar Mass =5o divided by (cl x 2) =50 divided by 71 =0.704 moles use: 1 mol = Mr in grams that is 35.5x2 g of Cl2 = 1 mol 71g of Cl2 = 1 mol therefore 50g of Cl2 = (1/71) x 50 =0.704 mol

How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
How many moles in 0.0688g Ag CL?
How many moles is in 0.0688 Ag Cl
How many grame are in 2.4 moles of sulfur?
one mole of sulfur has a mass of 32 g --- its atomic mass. so just multiply by 2,4 moles

What is the concentration of an AlCl3 solution if 150 ml of the solution contains 650 mg of Cl- ion?
Molarity = moles of solute/Liters of solution Atomic mass of Cl- = 35.453 molecular mass = 35.453amu molar mass = 35.453g/mol moles = 650mgCl- X 1molCl-/35.453gCl- = 0.0183341325135molCl- 0.0183341325135molCl-/150ml = 0.12222755009 1.22X10-1M
How many moles are in 1 g of Cl2?
# of Moles = Mass in grams divided by Molar Mass =5o divided by (cl x 2) =50 divided by 71 =0.704 moles use: 1 mol = Mr in grams that is 35.5x2 g of Cl2 = 1 mol 71g of Cl2 = 1 mol therefore 50g of Cl2 = (1/71) x 50 =0.704 mol
What compound contains 24.19 Cu 27.05 Cl and 48.76 oxygen?
CuCl19O73 Think about it as 100g. Therefore 24.19g of Cu, 27.05 g of Cl 48.76 g of O moles = mass/RAM Therefore moles of Cu = 24.19/29 = 0.834 Moles of Cl = 27.05/17 = 1.59 Moles of O = 48.76/8 = 6.095 To make biggest one a whole number, multiply by 12, and you get 1,19,73 Therefore CuCl19O73
