From the Periodic Table, Argon has an atomic weight of 39.948. One mole of any element is equal to its atomic weight in grams. So 1 mole of Ar = 39.948g of Ar.
Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar:
22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar

How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
What is the mass of 9.30 moles of SiH4 in grams?
first you set up your ratio; 9.3moles 1mole = 32g 9.3 is the number of moles you're trying to find 32 comes from adding the mass numbers of both elements; Si=28g H=1g, but there's four, so you multiply it by 4, hence the 32 now you crossmultiply; so multiply 9.3 by 32 you get 297.6, then divide by 1 so 9.3 moles SiH4 is 297.6g. follow the same pattern every time and you'll be fine; hope this helps
What is the mass in grams of three moles of H2SO4?
H2SO4 H= 1X2 = 2 S=32X1=32 O=16X4=64 TOTAL: 98 98x3= 294 GRAMS =))
How many grams of O2 are in 15 moles of O2. with work shown?
15 moles O2 (32 grams/1 mole O2) = 480 grams
How many grams are in 2.5 moles of sulfuric acid?
The mol mass of sulfuric acid is 98.078 g/mol, 98 g of sulfuric acid therefore contains 0.9992 moles. Using consistent significant figures and your calculations, 98 g sulfuric acid would be equal to 1.0 mol sulfuric acid.

How many moles are in 75 grams of sulfur?
For this you need the atomic mass of He. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.75.0 grams He / (4.00 grams) = 18.8 moles He
What is the number of moles in 32 grams of O2?
There are 1.0001 moles.
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
How many mols of sodium are present in 45.48 g of sodium?
# of moles = Mass÷ Formula weight Example: 6 grams of Carbon atoms Carbon has an atomic mass of 12 grams so according to the Equation # of moles = 6÷ 12 = 0.5 moles For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams. Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454 moles So for sodium, # of moles = 45.48 g ÷ 22.99g/mole = moles You divide!
What is the mass of 2.50 moles of oxygen gas?
The relationship between number of moles and mass is: n = m/MW Where n is the number of moles, m is the mass in grams and MW is the molecular weight (or molecular mass). Subsituting the numbers into the equation: 2.5 mol = m/32 (from O2(g), 16 from each oxygen) m = 2.5 * 32 = 80 grams This also means that there is approximately 1.5 x 1024 molecules of O2 in your sample.

What is the mass in grams of 2.50 mol of sulfur?
Sulfuric acid has a molecualr weight of 98 and so 2.5 moles would weigh 245 g
When carbon is burned in the presence of oxygen combine to produce carbon dioxide If you start with 6 grams of carbon and 11 grams of oxygen and they react completely how many grams of carbon dioxide?
C + O2 = CO2 So the theoretical number of moles are 1 each. number of moles is mass/molecular weight C = 6/12 which is 0.5 O2 = 11/32 which is 0.34375 Oxygen is the limiting reagent. So 0.34375 moles is reacted and this also gives 0.34375 moles CO2 no moles is mass over molecular mass grams is moles x molec mass 0.34375 x 44 = 15.125 grams CO2 formed. learn the technique. this is needed in science
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
How many grams of O2 are in 15 moles of O2. with work shown?
