Monitoring chemical reactions

What is the Avogadro constant?

A
  • Find moles of the known solution (n=cVn = cVn=cV).
  • Use the equation for mole ratio.
  • Calculate unknown concentration (c=nVc = \frac{n}{V}c=Vn​).
B

The number of particles in one mole: approximately 6.02×10236.02 \times 10^{23}6.02×1023.

C

The mass of particles in one mole: approximately 6.02×10236.02 \times 10^{23}6.02×1023 grams.

D

The number of particles in one gram: approximately 6.02×10236.02 \times 10^{23}6.02×1023.
