the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now primarily used in the production of the “anti-stick” polymer, Teflon. The molecular ...
What mass of PbSO4 is produced when 29.6 g of H2SO4 are reacted?Pb(s) + PbO2(s) + 2H2SO4(aq) → 2PbSO4(s) + 2H2O(ℓ) If 83.9 g of ZnO are formed, what mass of Mn2O3 is formed with it?Zn(s) + 2MnO2(s) → ZnO(s) + Mn2O3(s) If 14.7 g of NO2 are re...
For example, one molecule of nitric acid (HNO3) contains one nitrogen atom weighing 14.01 amu, one hydrogen atom weighing 1.008 amu, and three oxygen atoms weighing (3 × 16.00 amu) = 48.00 amu. The formula mass of nitric acid is therefore (14.01 amu + 1.008 amu + 48.00 amu) = 63.02...
formula units, etc. Applies to atoms, molecules, formula units, etc. With gases, you must be clear as to whether the With gases, you must be clear as to whether the gas is atomic or molecular ( O vs. O gas is atomic or molecular ( O vs. O 22 ). ). Use the molar mass of ...
2.When the formula of the compound and the atomic masses of the elements are given: When the formula of the compound and the atomic masses of the elements are given, the molecular mass of the compound can be calculated by adding the masses of all the elements present in the compound. The...
But these particles are extremely small objects, both in size and mass. If the mass of a small toothpick is about 1.00 × 10−2g, the mass of a hydrogen atom (1.67 × 10−24g) is 1.67 × 1022times lighter than the mass of the toothpick. Or if your mass is 10 kg, you are ...
