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.
What is the molar mass of PbSO4?
The molar mass of PbSO4 (lead(II) sulfate) is approximately 303.3 g/mol. This can be calculated by adding the molar masses of each element in the compound: lead (Pb) has a molar mass of 207.2 g/mol, sulfur (S) has a molar mass of 32.1 g/mol, and oxygen (O) has a molar mass of 16.0 g/mol.
What is the mass of 1 mol of rubidium?
According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.
What is the mass of 2.25 moles of magnesium sulfide?
To calculate the mass of 2.25 moles of magnesium sulfide (MgS), first determine its molar mass. Magnesium (Mg) has a molar mass of approximately 24.31 g/mol, and sulfur (S) has a molar mass of about 32.07 g/mol. Therefore, the molar mass of MgS is 24.31 g/mol + 32.07 g/mol = 56.38 g/mol. Multiplying the molar mass by the number of moles gives: 2.25 moles × 56.38 g/mol = 127.78 grams.
What is the molar mass of MgS?
The molar mass of MgS (magnesium sulfide) is calculated by adding the atomic masses of magnesium (Mg) and sulfur (S). The atomic mass of Mg is approximately 24.31 g/mol, and S is approximately 32.06 g/mol. Therefore, the molar mass of MgS is approximately 24.31 + 32.06 = 56.37 g/mol.
