- Discover molecular bulk of whole compound.
- Divide the component’s molar bulk by the entire unit bulk.
- Might currently have lots ranging from 0 and you will step 1. Multiply it by the one hundred% to obtain % constitution.
- The fresh new % structure of all factors within the a good ingredients must put doing 100%. From inside the a binary material, you will find the newest % of your very first function, upcoming carry out one hundred%-(% first ability) to find (% second function)
- If having fun with a great calculator, you could shop the general molar mass to an adjustable such as for example as the “A”. This may automate data, and relieve errors.
- \(P\): \(1 \times \,g/mol = \, g/mol\)
- \(Cl\): \(5 \times \, g/mol = \, g/mol\)
- \(PCl_5\): \(1 \moments \,g/mol + 5 \minutes \, g/mol = \, g/mol\)
