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
What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
What is the mass of 0.06 moles of zinc?
.06x molar mass of zinc which is the atomic mass so 3.9228 g
What is the mass in grams of 3 moles of water molecules?
249.72 g/mol
How many moles of hydrated copper sulphate are contained in 5.00g of the substance?
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
How many moles are there in 5 grams of potassium sulfate?
You have to use the equationnumber of moles = mass/Molar massn = 5/(39.1+32.1+64)n = 5/135.2number of moles = 0.04:)
How many moles of iodine are needed to react with 5 moles of potassium to create potassium iodide?
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
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
What is the mass of 5 moles of he atoms?
5 moles of helium He atoms is equivalent to 20,013 g.
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
What happens when water comes in contact with white copper sulphate crystals?
The white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.
What is the mass of 5 moles H2?
The mass of 5 mol H2 is 10,08 g.
What mass of Na2SO4 is needed to make 2.5L of a 2M solution?
In 1 litre (L) there are 2 moles (M) So in 2.5 L you have 2.5 X 2 = 5 moles. Remember the moles eq'n moles = mass(g) / Mr Hence mass(g) = moles X Mr Next refer to the Periodic Table in order to find the atomic masses of the atoms in sodium sulphate (Na2SO4) Na x 2 = 23 X 2 =46 S x 1 = 32 X 1 = 32 O x 4 = 16 X 4 = 64 46 + 32 + 64 = 142 ( The Mr of sodium sulphate). Substituting into the equation mass(g) = 5 moles X 142(Mr) mass(g) = 710 g is required. To make at a practical level. have approximately 1.5 litres of water . dissolve the whole mass of sodium sulphate (710 g) in this quantity of water. You will notice that the volume of the solution increases. Then add sufficient water to make a total volume of 2.5 litres. NB Do NOT add the sodium sulphate to 2.5 litres. Because then you will have more volume of less molarity .
What is the mass of 5 mole of ice?
5 Moles of ice is the same as 5 moles of water in another state.Therefore:5M H2O = 5 ((2x1.001) + 16.000) = 5 (18.001) = 90.005g
What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
What is the mass of 0.06 moles of zinc?
.06x molar mass of zinc which is the atomic mass so 3.9228 g
When blue salt of copper sulphate is heated it becomes colourless why?
actually blue salt of copper sulphate is chemically copper sulphate penta hydrate( CuSO4.5H2O ). blue coloure is due to thiese 5 moles of water . by heating this water evaporates and leaving CuSO4 which is colourless
