∙ 10y agoArgon (Ar) is a noble gas and exists as a monatomic element.
Atomic Mass of Ar = 39.9
Amount of Ar = 11.6/39.9 = 0.291mol
There are 0.291 moles of argon in a 11.6g sample.

∙ 14y ago90.0g x 1 mol Ar/39.948 g Ar = 2.25 mol Ar
You multiply the grams you have (90.0g) by the ratio of one mole of Ar and its corresponding molar mass as found on the periodic table (39.948g).

∙ 9y agoThe atomic mass of Ar is 39.9Amount of Ar = mass of pure sample/molar mass = 11.8/39.9 = 0.296mol
There are 0.296 moles of argon in a 11.8g pure sample.

How many moles of argon are in 24.7 g of argon?
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
How many moles are contained in 15.01 grams of argon?
Moles = mass in grams / atomic weight So moles in 15.01 g of Ar = 15.01 / 39.948 = 0.38 moles
How many moles of argon gas Ar are present in 5.6 liters of argon gas at standard conditions?
0.25 moles, approx.
What is the mass in grams of 3.2 moles of argon?
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
What is the number of moles of argon in 607 g of argon?
the equation is Xg multiplied by the moles/grams of X = moles of X (the grams cancel leaving you with moles) 607g Ar x 1 mole/ 39.95g = 15.19 moles
How many moles of Mg3PO42 are in 118g of Mg3PO42?
.45mol of Mg3PO42
How many ounces are in 118 grams?
118g = 4.162oz
How many moles are contained in 15.01 grams of argon?
Moles = mass in grams / atomic weight So moles in 15.01 g of Ar = 15.01 / 39.948 = 0.38 moles
How many moles of argon are in 24.7 g of argon?
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
How many moles of argon gas Ar are present in 5.6 liters of argon gas at standard conditions?
0.25 moles, approx.
What is the mass in grams of 3.2 moles of argon?
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
12.5 moles of magnesium equals?
Mass = Moles x Ar = 12.5 x 24 = 300g
How many moles are in 0.476 grams of bromine?
Mol = mass/Ar (relative atomic mass)For Bromine Ar is 79.9 g/mol.Mol= 0.476/79.9 = 5.96x10-3
How many atoms of Ar are in 0.44 moles of Ar?
(6.02*10^24)*0.44 = 2.6488*10^24In 1 mol of any element there are 6.02*10^24 atoms.
How many moles are in 2.10 kg of NaHCO3?
For this you need the atomic (molecular) mass of NaHCO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaHCO3=84.0 grams110 grams NaHCO3 / (84.0 grams) = 1.31 moles NaHCO3
Calculate the number of moles in 0.525 g of AgCl.?
moles= mass/Mr so 525 divided by the Mr of ZnCl-2 Mr of ZnCl-2= (Ar of Zn= 65.37)+(2 x Ar of Cl= 2 x 35.5= 71) = 136.37 moles= 525/136.37 = 3.85 moles to 3 significant figures. (in grams) divide the answer by 1000 to get mg so 3.85/1000= 0.00385 moles
What is the number of moles of argon in 607 g of argon?
the equation is Xg multiplied by the moles/grams of X = moles of X (the grams cancel leaving you with moles) 607g Ar x 1 mole/ 39.95g = 15.19 moles
