Empirical formula is the simplest ratio of components making up a compound.
The percentage composition of each element has been given
therefore the mass present of each element in 100 g of compound is
B N H
mass 40.28 g 52.20 g 7.53 g
number of moles
40.28 g / 11 g/mol 52.20 g / 14 g/mol 7.53 g / 1 g/mol
= 3.662 mol = 3.729 mol = 7.53 mol
divide the number of moles by the least number of moles, that is 3.662
3.662 / 3.662 3.729 / 3.662 7.53 / 3.662
= 1.000 = 1.018 = 2.056
the ratio of the elements after rounding off to the nearest whole number is
B : N : H = 1 : 1 : 2
therefore empirical formula for the compound is B₁N₁H₂
that can be written as BNH₂
The rate of movement increases, as they get faster with more energy.

Spanish System is not the name of a measurement system
WHAT IS MEASUREMENT SYSTEM?
- Measurement system are standard systems that are made up of collection is of units of measurement and guiding rules.
- Measurement system relates numerical values to physical quantities. There are three major system of measurements in use, they are:
- The international system of units (S.I units)
- The British imperial system
Hence, Spanish System is not one of the names of measurement of systems.
