How many atoms of sulfur are present in 155 g of sulfur?
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.
If you combine four atoms of oxygen gas and two atoms of hydrogen gas how many atoms of water and oxygen gas will be produced?
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
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 :)
How many O atoms are in Zn (clo3)2?
32
How many atoms of sulfur are in 3 g of sulfur?
no of atoms = weight of the given substance/ atomic mass of substance according to the question:- no of atoms = 3/32 answer
How many atoms in 32 moles of sulphur?
one mole contains 6.022 x 10^23 atoms. so multiply by 32
Approximately how many moles are in 300 grams of sulfur?
I mole of sulfur atoms is 32 g. Thus there are 300/32 moles in 300 g, i.e. 9.375 moles.
How many moles and number of atoms are there in 44 grams of H2O S 32 O 16 and H 1?
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
How many hydrogen atoms in 2 moles of hydrochloric acid?
2 moles - so 2 x 6.022 x 1023 = 1.2044 x 1024
How many grams of sodium sulfate will be formed if you start with 200grams of sodium hydroxide and you have an excess of sulfuric acid?
First write down the BALANCED reaction equation. 2NaOH + H2SO4 = Na2SO4 + 2H2O Note the molar ratios are 2:1::1:2 So two moles of NaOH produces one mole of Na2SO4 Next calculate tghe moles of NaOH mol(NaOH) = 200/(23 + 16 + 1) = 200/40 = 5 mol(NaOH) = 5 (This figure is equivalent to '2' above) mol(Na2SO4) = 5/2 = 2.5 ( Equivalent to '1' above) mol(Na2SO4) ; 2.5 = mass(g) / (2 x 23) + 32 + (4 x 16)) 2.5 = mass(g) / 142) mass*Na2SO4) = 2.5 x 142 = 355 g
How many atoms are in 4AgC2H3O2?
Here are 32 atoms in the formula unit.
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 moles in 112g of sulfur?
112/32 moles for every mole of sulfur there are 32g
How many atoms of sulfur are present in 155 g of sulfur?

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!
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 :)
