What is the mass of O?
The molar mass of oxygen (O) is approximately 16.00 g/mol.
What is the molar mass of lithium oxide li20?
The chemical formula for lithium oxide is ( \text{Li}2\text{O} ), not ( \text{Li}{20} ). To calculate the molar mass of lithium oxide, you add the molar masses of its components: lithium (Li) has a molar mass of about 6.94 g/mol, and oxygen (O) has a molar mass of about 16.00 g/mol. Thus, the molar mass of ( \text{Li}_2\text{O} ) is ( 2 \times 6.94 , \text{g/mol} + 16.00 , \text{g/mol} = 29.88 , \text{g/mol} ).
Is there 143g mol in 6.80g of al2o3?
To determine if there are 143 g/mol in 6.80 g of Al₂O₃, we first need to calculate the molar mass of Al₂O₃. The molar mass of Al₂O₃ is approximately 102 g/mol (with aluminum at about 27 g/mol and oxygen at about 16 g/mol). To find the number of moles in 6.80 g of Al₂O₃, we divide the mass by the molar mass: 6.80 g ÷ 102 g/mol ≈ 0.067 moles. Thus, there are no 143 g/mol in 6.80 g of Al₂O₃; the molar mass is actually around 102 g/mol.
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 the 3.7 mol pb02?
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 O?

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?
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.
