- New per cent composition of the many facets in an excellent substances need to create up to one hundred%. Within the a digital substance, there are this new % of your basic feature, then perform 100%-(% first feature) to acquire (% 2nd function)
- When the playing with a beneficial calculator, you might shop all round molar mass so you're able to a variable eg while the "A". This can speed up calculations, and reduce mistakes.
- \(P\): \(1 \minutes \,g/mol = \, g/mol\)
- \(Cl\): \(5 \times \, g/mol = \, g/mol\)
- \(PCl_5\): \(step one \moments \,g/mol + 5 \minutes \, g/mol = \, g/mol\)
