Multiply the moles given, by the Atomic Mass of chlorine and you have your answer. (3.55 Grams)
.75 moles times 64 grams/mols = 48 grams
Carbon tetraflouride or CF4, has a molar mass of 88.004 grams per mol. 1.32 mols of CF4 then has a mass of 116 grams
1 mole.
6 Mols of NO_2 This is due to there being 8 mols in the theoritical yeild and using the % yeild formula.
0.1 Moles

603 grams of mercury are equivalent to 3,006 moles.
.75 moles times 64 grams/mols = 48 grams
potassium dichromate- K2Cr2O7 12.5 grams K2Cr2O7 *(1 mol K2Cr2O7/294 grams K2Cr2O7)= .0425 mols K2Cr2O7 There's two mols of K (potassium) for every 1 mol of K2Cr2O7 (Potassium Dichromate) so you multiply the K2Cr2O7 by two to get mols of K .0425 mols K2Cr2O7*(2 mols K/1 mol K2Cr2O7)=.085 mols K Multiply by the molar mass of K to get grams .85 mols K*(39 grams/1 mol K)= 3.32 grams potassium
The mass is 0,324 g.
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
4.50 g(1/169.88) =.0265 mols
The answer is 315,575 g.
approx. 45.6
To convert the number of chloride atoms to mols of chlorine atoms, simply multiply by Avogadro's number. This number is 6.022E23. Note that chlorine typically exists as a diatomic molecule, consisting of two chlorine atoms.
17.24 g Sr * 1 mol/87.62 g Sr = 0.1968 mols Sr
It's 97g/195.1g Pt = .497 .497 x 6.022x10^23= 2.993 mols/atom.
