What is the mass percentage of each element in the compound sodium hydroxide?
Molar mass Na: 23 g/mol O : 16 g/mol H : 1 g/mol Total NaOH: 40 g/mol Mass percentage %Na: 23/40 = 57.5% %O : 16/40 = 40% %H : 1 /40 = 2.5%
What is the formula mass of Na3NO2?
To calculate the formula mass of Na3NO2, we need to add the atomic masses of each atom in the compound. Na (sodium) has a mass of 22.99 g/mol, N (nitrogen) has a mass of 14.01 g/mol, and O (oxygen) has a mass of 16.00 g/mol. Therefore, the formula mass of Na3NO2 = 3(Na) + 1(N) + 2(O) = 3(22.99) + 14.01 + 2(16.00) = 85.97 g/mol.
What is the formula mass for NaClO?
The formula mass for NaClO (sodium hypochlorite) is calculated by adding the atomic masses of each element in the compound: Na (sodium) = 22.99 g/mol Cl (chlorine) = 35.45 g/mol O (oxygen) = 16.00 g/mol Formula mass = 22.99 + 35.45 + 16.00 = 74.44 g/mol
What is the mass of O?
The molar mass of oxygen (O) is approximately 16.00 g/mol.
What is the molar mass of mg o?
The molar mass of magnesium oxide (MgO) is approximately 40.3 g/mol.
What is the mass of NaNO3?
1 mol Na X (22.99 Na / mol Na) = 22.99 g Na1 mol N X (14.01 g N / mol N) = 14.01 g N3 mol O X (16.00 g O / mol O) = 48.00 g OMolar mass of NaNO3 = 85.00 g/mol
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What percentage composition of Al2O3 is aluminum?
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%
What is the formula mass of h20?
The formula mass of H2O (water) is calculated by adding the atomic masses of the elements present in the compound. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1 and 16, respectively. Therefore, the formula mass of H2O is 1 (atomic mass of H) * 2 (number of hydrogen atoms) + 16 (atomic mass of O) = 18.
What is the molar mass of lithium oxide Li2O?
The molar mass of lithium oxide (Li2O) is calculated by adding the molar masses of lithium (Li) and oxygen (O). Molar mass of Li = 6.94 g/mol Molar mass of O = 16.00 g/mol Molar mass of Li2O = 2*(molar mass of Li) + molar mass of O = 2*(6.94) + 16.00 = 14.88 + 16.00 = 30.88 g/mol
What is the mass of 0.0250 mol of P2O5?
3.55g
What is the molar mass of hydrogen perxoide?
The molar mass of hydrogen peroxide (H₂O₂) is approximately 34.01 g/mol.
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass percent of oxygon (O) in SO2?
The molar mass of SO2 is 64.06 g/mol. Oxygen contributes 32 g/mol to this molar mass, so the mass percent of oxygen in SO2 is (32 g/mol / 64.06 g/mol) x 100, which is approximately 50%.
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
To find the mass of 0.7891 mol of ferric oxide (Fe2O3), you need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Multiply the molar mass by the number of moles to find the mass: 0.7891 mol * 159.69 g/mol ≈ 125.94 g. Therefore, the mass of 0.7891 mol of Fe2O3 is approximately 125.94 grams.
