To work out moles you do:
Mass/molecular mass
37.8/10.811
= 3.4964388123
= 3.50 (3 s.f)
3.50mol
Mass/molecular mass
37.8/10.811
= 3.4964388123
= 3.50 (3 s.f)
3.50mol
The total number of moles of boron in 37.8 grams is 3.50 mols.
How can we find moles in Boron?
- Mole, also spelled mol, in chemistry, is a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
- The unit of mol is SI.
- Total number of moles = Mass/molecular mass
= 37.8/10.811
= 3.4964388123
- So, 3.4964388123 moles means approximately 3.50 mols.
So, The total number of moles of boron in 37.8 grams is 3.50 mols.
