Atomic mass is the relative weight of the protons and neutrons in an atom. Remember, atoms are composed of protons, neutrons, and electrons. Electrons are much smaller than either protons or neutrons, so we consider their mass negligible. The unit used for atomic mass is atomic mass units (...
0.4 moles of NaOH has a mass found by the equation: mass of NaOH = number of moles× relative molecular of NaOH mass of NaOH =0.4×(23+16+l)=0.4×40=16g That is, the mass of sodium hydroxide required is 16 g. 6 When applied to gases, the molar volume of any gas is defined as...
