To find the mass of 3.7 moles of PbO2 (lead(IV) oxide), we first need to calculate its molar mass. The molar mass of PbO2 is approximately 207.2 g/mol (for Pb) + 2 × 16.0 g/mol (for O) = 239.2 g/mol. Therefore, the mass of 3.7 moles of PbO2 is 3.7 mol × 239.2 g/mol = 884.04 grams.

What is the mass of 0.50 mol of aluminum foil?
To find the mass of 0.50 mol of aluminum foil, we first need the molar mass of aluminum, which is approximately 27 g/mol. Therefore, the mass can be calculated using the formula: mass = moles × molar mass. For 0.50 mol of aluminum, the mass would be 0.50 mol × 27 g/mol = 13.5 grams.
Calculate NaCl in atomic mass?
By adding up the mass numbers of Na (23) and Cl (35 or 37). It is determined by the total of numbers of protons (11 and 17 respectively) and of neutrons (12 and 18 or 20), however it is not a sensible exercition to do, you cannot calculate anything with this figure.
Calculate the mass in grams of 2.60 mol of potassium chloride (KCl)?
To calculate the mass of 2.60 mol of potassium chloride (KCl), first determine its molar mass. The molar mass of KCl is approximately 74.55 g/mol (39.10 g/mol for K and 35.45 g/mol for Cl). Thus, the mass can be calculated using the formula: mass = moles × molar mass. Therefore, the mass of 2.60 mol of KCl is 2.60 mol × 74.55 g/mol = 193.83 grams.

what is the mass of 0.555 mol magnesium fluoride?
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.
