To find the molar mass of POCl₃ (phosphoryl chloride), you need to sum the atomic masses of its constituent elements: phosphorus (P: approximately 30.97 g/mol), oxygen (O: approximately 16.00 g/mol), and chlorine (Cl: approximately 35.45 g/mol). The molar mass of POCl₃ is calculated as follows: 30.97 g/mol (P) + 16.00 g/mol (O) + 3 × 35.45 g/mol (Cl) = 137.32 g/mol. Therefore, the molar mass of 0.317 mol of POCl₃ is 0.317 mol × 137.32 g/mol = 43.56 g (approximately).

How mane moles of pocl3 are there in 10.0 grams of pocl3?
To find the number of moles of POCl3 in 10.0 grams, you first need to calculate the molar mass of POCl3. The molar mass is approximately 30.97 g/mol (P) + 16.00 g/mol (O) + 3 × 35.45 g/mol (Cl) = 137.32 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), you would calculate moles = 10.0 g / 137.32 g/mol, which is approximately 0.073 moles of POCl3.

To calculate the molar mass of Mn₂Se₇, you need the atomic masses of manganese (Mn) and selenium (Se). The molar mass of Mn is approximately 54.94 g/mol, and for Se, it is about 78.96 g/mol. Thus, the molar mass of Mn₂Se₇ is calculated as follows: (2 × 54.94 g/mol) + (7 × 78.96 g/mol) = 109.88 g/mol + 552.72 g/mol = 662.60 g/mol. Therefore, the molar mass of Mn₂Se₇ is approximately 662.60 g/mol.
Calculate the mass in grams of 2.60 mol of potassium chloride?
To calculate the mass of 2.60 mol of potassium chloride (KCl), first determine its molar mass. The molar mass of K (potassium) is approximately 39.10 g/mol, and Cl (chlorine) is about 35.45 g/mol, giving KCl a molar mass of about 74.55 g/mol. Multiplying the number of moles by the molar mass, we have 2.60 mol × 74.55 g/mol = 193.83 g. Therefore, the mass of 2.60 mol of potassium chloride is approximately 193.83 grams.
