The answer is 6,176.10e23 atoms of chlorine.
Chlorine (the element) has an Atomic Mass of 35.45 g/mole. Thus, 45.12 g x 1 mol/35.45 g = 1.273 moles. (4 sig. figs.)
If you mean chlorine gas, the answer will be 1/2 of that.
75,10 g of chlorine = 2,1183 moles
64 moles of chlorine atoms would be 64 x 35.5 grams, i.e. 2272 grams. If you meant the substance chlorine, which consists of Cl2 molecules, it would be 4544 grams.
500 grams of radium is equal to 2,21 moles.
2.8 moles of gold would be 550g of gold. Multiplying the amount of moles by the molar mass (197.0 grams/moles) will give you the grams by cancelling out the moles units.
there is .42 moles
75,10 g of chlorine = 2,1183 moles
Multiply the moles given, by the atomic mass of chlorine and you have your answer. (3.55 Grams)
64 moles of chlorine atoms would be 64 x 35.5 grams, i.e. 2272 grams. If you meant the substance chlorine, which consists of Cl2 molecules, it would be 4544 grams.
The answer is it's atomic mass converted to grams... Chlorine has an atomic mass of 35.45 So 1 mol of chlorine would be 35.45g you have 142g of it, so you divide 142 by 35.45 and get 4.005 moles of chlorine
The balanced chemical equation for the reaction between calcium and chlorine gas to produce calcium chloride is: Ca + Cl2 -> CaCl2. From this equation, we can see that one mole of calcium reacts with one mole of chlorine gas to produce one mole of calcium chloride. The molar mass of calcium is 40.08 g/mol and the molar mass of chlorine gas is 70.90 g/mol. This means that 10.0 grams of calcium is equivalent to 0.249 moles of calcium and 20.0 grams of chlorine gas is equivalent to 0.282 moles of chlorine gas. Since the ratio of calcium to chlorine gas in the balanced chemical equation is 1:1, this means that 0.249 moles of calcium would react completely with 0.249 moles of chlorine gas, leaving an excess of 0.033 moles (or 2.34 grams) of chlorine gas. The limiting reactant in this reaction is calcium, and the maximum amount of calcium chloride that can be produced is equivalent to the number of moles of the limiting reactant, which is 0.249 moles (or 27.8 grams) of calcium chloride.
The atomic mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
16 grams of oxygen how many moles is 0,5 moles.
The gram molecular mass of Cl2 is 70.906, twice the atomic mass of chlorine atoms. Therefore, 79.3 grams of Cl2 contains 79.3/70.906 or 1.12 moles, to the justified number of significant digits.
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
.75 moles times 64 grams/mols = 48 grams
53 grams ÷ 18.01 grams/mole = 2.94 moles
180 grams of water is 10 moles of water.
