no. moles = mass / molecular weight
molecular weight = 64.06
mass = 28.4
28.4 / 64.06 =

How many atoms of sulfur are there in 2 mol of sulfur?
For this you need the atomic mass of S. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.4 mole S × (32.1 grams) = 77.0 grams S
How many atoms are there in 5.10 grams of sulfur?
You will need to convert to moles, and then atoms. Here is the equation: (5.10 grams over one) times (1 mol S over 32.06 g S) times (6.022 X 10 23 atoms over 1 mol S) the last part of the equation is read six point zero two two times ten to the twenty third.
How many grams of calcium carbonate are needed to produce 93.0 L of carbon dioxide at STP?
At STP one mole of any gas occupies 22.4 L. The equation for the reaction is CaCO3(S) - -> CaO (s) + CO2 (g). Moles of CO2 in 93.0 L is 93/22.4 = 4.15 moles, the ratio of moles of CaCO3 and CO2 is 1:1, therefore 4.15 moles of CaCO3 will be required. 1 mole of CaCO3 is equal to 100.087 g/mol. Therefore, 4 .15 moles will have 415.2 grams.
HOW many moles are in 4.5 moles of sodium fluoride?
there are 4.5 moles
How much heat will be released when 6.44 grams of sulfur reacts with excess oxygen?
delta H=[2(-791.4kJ)]-o.oo-o.oo delta H=-1582.8 kJ/mol (6.44g S x 1mole S x 2 moles SO3) / (32.06g S x 1mole S)=0.200moles SO3 (0.200mole x -791.4) / (2 moles) = -79.14
How many moles in 284 grams of potassium?
Potassium has atomic number 39.1.Amount of K in 284g sample = 284/39.1 = 7.26molThere are 7.26 moles of potassium in a 284g sample.
What has the author Cathy Covert written?
Cathy Covert has written: 'Mental retardation' -- subject(s): Child, Mental retardation
How many moles are in 3.3 moles of K2S?
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
How many moles are in 6.5 grams of sulfur S?
6,5 grams of sulfur S are equal to 0,203 moles.
How many sulfur molecules are there in 6.35 moles of S?
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
How many moles of S are in 22.9g of C6H10S?
Here are 0,2 moles sulfur.
How many moles OF s are present 7.71g of s?
7.71 grams sulfur (1 mole S/32.07 grams) = 0.2404 moles of sulfur
What are the release dates for C-A-T-s - Covert Anti-Espionage Team 2012?
C-A-T-s - Covert Anti-Espionage Team 2012 was released on: USA: 8 July 2012
How many moles in 300.0g S?
300 g sulfur is equivalent to 9,36 moles.
What are some parts of a chemical change?
Depict moles eg: Fe2O3(s) + 3CO(g)--> 2Fe(s) + 3CO2(g) 1 mole of Fe2O3 4 moles of CO 2 moles of Fe 3 moles of CO2
What is the mass of 2.65 moles of Ag(s)?
The mass of 2,65 Ag moles is 285,85 g.
How many moles of H will react with 1.72 moles of S?
Hydrogen reacts with sulfur in the proportions dictated by this equation:H2 + S --> H2S. The reactants are in a 1:1 proportion with each other, so 1.72 moles of hydrogen will react with 1.72 moles of sulfur.
