The molar mass of sodium carbonate is approximately 106 grams per mole.
Benzene has a molar mass of approximately 78 grams per mole. This is calculated by adding together the molar mass of each carbon atom (12 grams per mole) and each hydrogen atom (1 gram per mole) in the chemical formula C6H6.
The formula for iron (II) sulfate is FeSO4.H2O, and its gram formula unit mass is 169.92. Therefore, 3.52 formula units of this compound have a mass of 598 grams, to the justified number of significant digits.
The molar mass of sodium carbonate (Na2CO3) can be calculated by adding the atomic masses of its constituent elements. The atomic masses of sodium (Na), carbon (C), and oxygen (O) are approximately 23 g/mol, 12 g/mol, and 16 g/mol, respectively. Therefore, the molar mass of sodium carbonate is approximately 105 g/mol when rounded to the nearest gram.
To calculate the molar mass of aluminum sulfate (Al2(SO4)3), you need to sum the atomic masses of all the elements in the formula. The atomic mass of aluminum (Al) is 26.98 g/mol, sulfur (S) is 32.07 g/mol, and oxygen (O) is 16.00 g/mol. The molar mass of Al2(SO4)3 = 2(26.98) + 3(32.07 + 4(16.00)) = 2(26.98) + 3(32.07 + 64.00) = 54.96 + 3(96.07) = 54.96 + 288.21 = 343.17 g/mol. Therefore, the molar mass of aluminum sulfate to the nearest gram is 343 g/mol.
To the nearest gram, molar mass of aluminium carbonate is 234 g/mol.
To calculate the molar mass of aluminum sulfate (Al₂(SO₄)₃), we need to sum the masses of its constituent elements. Aluminum (Al) has a molar mass of approximately 27 g/mol, sulfur (S) about 32 g/mol, and oxygen (O) around 16 g/mol. The formula contains 2 aluminum atoms, 3 sulfur atoms, and 12 oxygen atoms: [ (2 \times 27) + (3 \times 32) + (12 \times 16) = 54 + 96 + 192 = 342 \text{ g/mol} ] Thus, the molar mass of aluminum sulfate is approximately 342 g/mol.
The molar mass of sodium carbonate to the nearest gram is 105,99 g.
The molar mass of nitrogen dioxide is 46.0055 g.

The molar mass of benzene is 76,11 g.
The molar mass of sodium carbonate is approximately 106 grams per mole.
The molar mass of benzene (C6H6) is approximately 78 grams per mole.
The molar mass of nitrogen dioxide (NO2) is approximately 46 grams per mole.
The molar mass of nitrogen (N) is approximately 14 grams/mole, and the molar mass of oxygen (O) is approximately 16 grams/mole. Therefore, the molar mass of nitrogen dioxide (NO2) is 14 + (2*16) = 46 grams/mole to the nearest gram.
The molar mass of nitrogen dioxide is 46.0055 g.
