978 g calcium contain 24,4 moles.
29,0 g of calcium is equal to 0,723 moles.
67,4 g HCl is equivalent to 1,85 moles.
14,84 g magnesium are equivalent to 0,61 moles.
97,5 g of oxygen is equal to 5,416 moles.
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.
To find the number of atoms in 165 g of calcium, you first need to determine the number of moles by dividing the mass by the molar mass of calcium (40.08 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 167 mole of CO2 has 167 mole of carbon atoms.
The formula is: number of moles = g Be/9,012.
To calculate the number of atoms in 165 grams of calcium, you need to first determine the number of moles using the molar mass of calcium. Calcium has a molar mass of approximately 40.08 g/mol. Once you have the number of moles, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
14,84 g magnesium are equivalent to 0,61 moles.
97,5 g of oxygen is equal to 5,416 moles.
978 g calcium contain 24,4 moles.
67,4 g HCl is equivalent to 1,85 moles.
29,0 g of calcium is equal to 0,723 moles.
573,28 of g of AgCI is equivalent to 4 moles.
27.4 g H2O x 1 mole/18 g = 1.52 moles
