1.	Example 3.5 Calculate the number ofparticles in each of thefollowing0) 46 g of Na atoms (number frommass)
Answer» a)46g of Na atomatomic mass of Na=23uNumber of particles=Number of Moles x N⇒(given weight/ Gram atomic weight) x 6.023 x 10²³=(46/23)x 6.023 x 10²³=2x 6.023 x 10²³⇒12.046 x 10 ²³Na particles∴46 g of Na contains 12.044 x 10 ²³ wrong
