Question

How to solve mole concept numericals

Answer 1

Answer:

Apply these formulas

# n = N/NA ...

# Molar mass of a Substance = (Mass of the Substance in grams)/(Number of Moles) ...

# Number of Moles = (Mass of the Sample)/(Molar Mass) ...

#Number of Atoms or Molecules = (Number of Moles)*(6.022*1023) ...

# 1 amu = (1gram)/(6.022*1023) = 1.66*10-24 grams.

Hope it helps u
