To find the mass of 0.555 mol of magnesium fluoride (MgF₂), first determine the molar mass. The molar mass of Mg is approximately 24.31 g/mol, and that of F is about 19.00 g/mol, giving MgF₂ a total molar mass of about 24.31 + (2 × 19.00) = 62.31 g/mol. Therefore, the mass of 0.555 mol of MgF₂ is calculated as 0.555 mol × 62.31 g/mol ≈ 34.59 g.

What is the percent composition of magnesium (mg) in mg0?
To find the percent composition of magnesium (Mg) in magnesium oxide (MgO), first determine the molar masses: magnesium has a molar mass of approximately 24.31 g/mol, and oxygen has a molar mass of about 16.00 g/mol. The molar mass of MgO is roughly 40.31 g/mol (24.31 g/mol + 16.00 g/mol).

Magnesium oxide decomposes into magnesium and oxygen If 16.12 of magnesium oxide decomposes to form 9.72 of magnesium what mass of oxygen gas is also released in the reaction?
To find the mass of oxygen gas released, we can first find the mass of magnesium in 16.12 g of magnesium oxide (molar mass of MgO = 40.31 g/mol) and then subtract it from 9.72 g to find the mass of oxygen. Find the moles of magnesium in 16.12 g of MgO: 16.12 g / 40.31 g/mol = 0.4 mol Mg Mg and O are in a 1:1 molar ratio in MgO, so 0.4 mol of Mg is equal to 0.4 mol of O Calculate the mass of oxygen: 0.4 mol x 16 g/mol = 6.4 g Therefore, 6.4 g of oxygen gas is also released in the reaction.
