What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
How many moles are there in 5gram of sulphur?
To find the number of moles in 5 grams of sulfur, you need to divide the mass of the sample by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, 5 grams of sulfur would be equal to 0.156 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
How do you calculate number of moles in 1 teaspoon of sodium sulphide?
To calculate the number of moles in 1 teaspoon of sodium sulfide (Na₂S), you first need to know the mass of sodium sulfide in that teaspoon. Typically, a teaspoon holds about 5 grams of a substance, but this can vary based on the density of the compound. Once you have the mass, you can use the molar mass of Na₂S (approximately 78.04 g/mol) to find the number of moles by using the formula: moles = mass (g) / molar mass (g/mol). For example, if 1 teaspoon is 5 grams, then moles of Na₂S = 5 g / 78.04 g/mol ≈ 0.064 moles.
How many moles are there in 5 grams of potassium sulfate?
To find the number of moles in 5 grams of potassium sulfate (K2SO4), first calculate the molar mass of K2SO4 by adding the atomic masses of potassium (K), sulfur (S), and four oxygen (O) atoms. Then, divide the given mass (5 grams) by the molar mass of K2SO4 to get the number of moles.
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 5 grams of silicon dioxide?
To determine the number of moles in 5 grams of silicon dioxide (SiO2), you first need to calculate the molar mass of SiO2. The molar mass of SiO2 is 60.08 g/mol. Then, use the formula Moles = Mass / Molar mass to find that there are approximately 0.083 moles in 5 grams of SiO2.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
How many moles are there in 5gram of sulphur?
To find the number of moles in 5 grams of sulfur, you need to divide the mass of the sample by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, 5 grams of sulfur would be equal to 0.156 moles.
What is the mass of 5 moles of he atoms?
5 moles of helium He atoms is equivalent to 20,013 g.
What is the mass of 5 moles H2?
The molar mass of H2 is 2 g/mol. To find the mass of 5 moles of H2, you would multiply the molar mass by the number of moles: 2 g/mol * 5 mol = 10 grams.
How many moles of 5grams of oxalic acid?
To calculate the number of moles in 5 grams of oxalic acid (C2H2O4), first determine the molar mass of oxalic acid, which is 90.03 g/mol. Then, divide the mass (5 grams) by the molar mass to get the number of moles. In this case, 5 grams is equal to approximately 0.055 moles of oxalic acid.
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 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 gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
Moles of saccharin are there in 0.016 g?
To calculate the moles of saccharin in 0.016 g, you first need to know the molar mass of saccharin, which is 183.18 g/mol. Then, use the formula: moles = mass / molar mass moles = 0.016 g / 183.18 g/mol = 0.000087 moles of saccharin.
