Molar mass of magnesium is 24gmol-1. mass of 1.5 mg mole 36g.
To find the number of moles of magnesium, we first need to calculate the molar mass of magnesium, which is 24.305 g/mol. Next, we convert the mass of the strip to moles using the formula moles = mass/molar mass. Plugging in the values, the number of moles of magnesium in the strip is 0.00463 moles.
The molar mass of magnesium sulfate (MgSO₄) is approximately 120.37 g/mol. To find the mass of 0.3 moles, you multiply the number of moles by the molar mass: 0.3 moles × 120.37 g/mol = 36.11 grams. Therefore, the mass of 0.3 moles of magnesium sulfate is about 36.11 grams.
The mass of 15 moles of tungsten is 2.757,6 g.
The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
First, determine the molar mass of magnesium nitrate (Mg(NO3)2) by adding the atomic masses of magnesium, nitrogen, and oxygen. Then, divide the given mass (9.00g) by the molar mass to find the moles of magnesium nitrate.
To find the number of moles of magnesium, we first need to calculate the molar mass of magnesium, which is 24.305 g/mol. Next, we convert the mass of the strip to moles using the formula moles = mass/molar mass. Plugging in the values, the number of moles of magnesium in the strip is 0.00463 moles.
To determine how many moles of magnesium are in a sample of 56.4 g, you would first calculate the molar mass of magnesium (about 24.3 g/mol). Then, divide the mass of the sample by the molar mass to obtain the number of moles present (around 2.32 moles in this case).
The molar mass of magnesium sulfate (MgSO₄) is approximately 120.37 g/mol. To find the mass of 0.3 moles, you multiply the number of moles by the molar mass: 0.3 moles × 120.37 g/mol = 36.11 grams. Therefore, the mass of 0.3 moles of magnesium sulfate is about 36.11 grams.
To calculate the number of moles of magnesium used, you divide the mass of magnesium by its molar mass. The molar mass of magnesium is approximately 24.31 g/mol. For example, if you have 12.15 grams of magnesium, you would divide 12.15 by 24.31 to find that you have 0.5 moles of magnesium.
To find the molarity of 48.6 grams of magnesium, you first need to determine the number of moles of magnesium in 48.6 grams using the molar mass of magnesium (24.305 g/mol). Then, you divide the moles of magnesium by the volume of the solution in liters to get the molarity.
The molar mass of magnesium chloride MgCl2 is 95.21 g/mol. To find the mass of 6.80 moles, you would multiply the number of moles by the molar mass: 6.80 moles * 95.21 g/mol = 647.868 g. Therefore, the mass of 6.80 moles of MgCl2 is 647.868 grams.
If you think to the mass of 88,1 moles of magnesium this is 2141,27 g.
To calculate the number of moles in 165 g of magnesium, we first need to find the molar mass of magnesium, which is 24.305 g/mol. Then, we divide the given mass by the molar mass to find the number of moles. So, 165 g / 24.305 g/mol ≈ 6.79 moles of magnesium.
The mass of 15 moles of tungsten is 2.757,6 g.
The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Mg= 24.3 grams35.0 grams Mg / (24.3 grams) = 1.44 moles Mg
To find the number of moles in 13.5 grams of magnesium nitrate, you need to divide the given mass by the molar mass of magnesium nitrate. The molar mass of magnesium nitrate (Mg(NO3)2) is 148.31 g/mol. Moles of magnesium nitrate = 13.5 grams / 148.31 g/mol ≈ 0.091 moles
