one mole contains 6.022 x 10^23 atoms. so multiply by 32
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
H2O: 44g x 1 mol/18 g = 2.44 moles and 2.44 moles x 6.02x10^23 atoms/mole = 1.5x10^24 atomsS-32: 44g x 1mol/32g = 1.375 moles and 1.375 moles x 6.02x10^23 atoms/mole = 8.3x1^23 atomsO-16: 44g x 1 mol/16g = 0.6875 moles and 0.6875 moles x 6.02x10^23 atoms/mol = 4.2x10^23 atomsH-1: 44g x 1mol/1g = 44 moles and 44 moles x 6.02x10^23 atoms/mole = 2.6x10^25 atoms
Here are 32 atoms in the formula unit.
Sulphur: symbol S; at. no. 16; at. wt. 32: One Gram Mole of Sulphur weights 32 gm.
# 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!

I mole of sulfur atoms is 32 g. Thus there are 300/32 moles in 300 g, i.e. 9.375 moles.
H2O: 44g x 1 mol/18 g = 2.44 moles and 2.44 moles x 6.02x10^23 atoms/mole = 1.5x10^24 atomsS-32: 44g x 1mol/32g = 1.375 moles and 1.375 moles x 6.02x10^23 atoms/mole = 8.3x1^23 atomsO-16: 44g x 1 mol/16g = 0.6875 moles and 0.6875 moles x 6.02x10^23 atoms/mol = 4.2x10^23 atomsH-1: 44g x 1mol/1g = 44 moles and 44 moles x 6.02x10^23 atoms/mole = 2.6x10^25 atoms
2 moles - so 2 x 6.022 x 1023 = 1.2044 x 1024
There are more atoms of sulfur in 16 grams than there are atoms of iron in 56 grams.
The gram-atomic mass of sulphur is 32 and that of oxygen is 16, to two significant digits. Therefore, the mass of oxygen with the same number of atoms as 64 grams of sulphur can be found from the proportion m/64 = 16/32, or m = 32 grams.
Here are 32 atoms in the formula unit.
112/32 moles for every mole of sulfur there are 32g
93,341,000,000,000,000,000,000,000 or 933.41 x 1023 atoms of arsenic. You just take Avogadro's number (6.022 x 1023) and multiply 6.022 by the number of moles (155) and then multiply the product by 1023.
Sulphur: symbol S; at. no. 16; at. wt. 32: One Gram Mole of Sulphur weights 32 gm.
I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
#1 Remember the moles equation , which is moles = mass(g) /Mr #2 Mr is the relative molecular mass of the given substance. For SO2 it is' 1 x s = 1 x 32 = 32 2 O = 2 x 16 = 32 32 + 32 = 64 Hence substituting moles(SO2) = 2.56g / 64 = moles = 0.04 moles NB When writing chemical formula, single letter symbols are ALWAYS a CAPITAL letter. Hence sulphur is 'S' and oxygen is 'O'. NOT 'o' A double letter symbol is written as , 1st leter is a capital letter and the second letter is small / lower case. e.g. Sodium is 'Na'.
