Aluminum nitrate is a solid compound according to the Standard Temperature and Pressure. Formula of the compound is Al(NO3)3. There are many different physical properties of this compound. For example, aluminum nitrate has molar mass which is equal to 212.996 g/mol.
How do you determine molar mass?
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
What is molar mass of CaO?
Molar mass of CaO, Calcium Oxide is 56.0774 g/mol. Calcium oxide is a white crystalline solid. In chemical formula you may use: Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. CaO.
Explanation: In 1 formula unit of Al(NO3)3 , there are (clearly!) 9 atoms of oxygen, 3 nitrogen atoms, and 1 aluminum atom.
What is the mass of 0.5 moles of CaCO3?
Solution — Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.
