How many moles of magnesium are in a sample of 56.4 of magnesium?
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).
How many moles of magnesium are 12.04 x 10 23 atoms?
1 mole Mg = 6.022 x 1023 atoms Mg 12.04 x 1023 atoms Mg x 1mol Mg/6.022 x 1023 atoms Mg = 1.999 moles Mg
How do you expand these compounds 3MgCL2?
To expand the compound 3MgCl2, you need to break it down into its constituent elements. In this case, Mg represents magnesium and Cl represents chlorine. The subscript 3 indicates that there are three magnesium atoms and six chlorine atoms in the compound. Therefore, the expanded form of 3MgCl2 is 3 magnesium atoms and 6 chlorine atoms.
How many oxygen atoms in 0.800 moles MgO?
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
How many moles are in 4.515x10 24 atoms of magnesium?
4,515.10e24 atoms of magnesium is equal to 7,5 moles.

How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen Here is the formula 2 Mg plus O 2 is equal to 2 Mg O?
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
How many moles of magnesium are in a sample of 56.4 of magnesium?
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).
How many moles of fluorine molecules react with one mole of magnesium atoms?
One: The formula for magnesium fluoride is MgF2. Since each mole of fluorine molecules, which have the formula F2, contains two moles of fluorine atoms, one mole of each is the right ratio.
How many atoms in 4 Mg(OH)2?
In 4 moles of magnesium hydroxide, Mg(OH)₂, there are a total of 20 atoms. Each formula unit of Mg(OH)₂ contains 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms, totaling 5 atoms per unit. Therefore, for 4 moles, you calculate 4 moles × 5 atoms/mole = 20 atoms.
How many moles of magnesium are 12.04 x 10 23 atoms?

What is the number of moles present in 165 g of magnesium?
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.
