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.
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.
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.
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.
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.

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.
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
molar mass is 318 g/mol (2X27)+3(2X12+4X16)=318g/mol
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
The molar mass of Cesium Chloride (CsCl) is 168.36 g/mol. This is calculated by adding the molar mass of cesium (Cs) which is 132.91 g/mol and chlorine (Cl) which is 35.45 g/mol.
The molar mass of AlOH3 is calculated by adding the atomic masses of each element in its chemical formula. Aluminum (Al) has a molar mass of 26.98 g/mol, oxygen (O) has a molar mass of 16.00 g/mol, and hydrogen (H) has a molar mass of 1.01 g/mol. Therefore, the molar mass of AlOH3 is 78.02 g/mol.
The molar mass of ammonia gas (NH3) is approximately 17.03 g/mol.
The molar mass of BaSO4 (Barium sulfate) can be calculated by adding the molar mass of each element present in the formula: Ba (barium) has a molar mass of 137.33 g/mol, S (sulfur) has a molar mass of 32.06 g/mol, and O (oxygen) has a molar mass of 16.00 g/mol. Adding these together gives a molar mass of 137.33 + 32.06 + (4 * 16.00) = 233.37 g/mol for BaSO4.
Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol Molar Mass of O: 3(16.0g/mol) = 48.0g/mol Molar Mass of compound: 102.0g.mol (54.0g/mol / 102.0g/mol) x 100% = 52.9%
