Question

Calculate mass of Avogadro number of particles of sodium chlorine

Answer 1

Key Concepts. 1 mole of any substance contains 6.022 × 1023 particles. 6.022 × 1023 is known as the Avogadro Number or Avogadro Constant and is given the symbol NA (1) N = n × NA. N = number of particles in the substance. To find the number of particles, N, in a substance: To find the amount of substance in moles, n :

Answer 2

Hay mate here is your answer ✌❤☺



Calculate the molecular massof a compound as the sum of the atomic masses of its elements.

So, one mole of water (6.022 x 10 23molecules) has a mass of 18.02 g.

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

Hope it will help you ☺❤
