  2. If the playing with a calculator, you could shop all round molar bulk so you’re able to a variable particularly as “A”. This can speed up computations, and reduce mistakes.
  • \(P\): \(1 \times \,g/mol = \, g/mol\)
  • \(Cl\): \(5 \moments \, g/mol = \, g/mol\)
  • \(PCl_5\): \(1 \minutes \,g/mol + 5 \moments \, g/mol = \, g/mol\)
