Calculate the no of moles present in : a)18g of mg (mg=24)b)12.044 x 10^22 no of neon atom

Calculate the no of moles present in : a)18g of mg (mg=24)b)12.044 x 1

1.	Calculate the no of moles present in : a)18g of mg (mg=24)b)12.044 x 10^22 no of neon atom
Answer» A) No. of MOLES = GIVEN MASS/ molar mass = 18/24 = 3/4 =0.75 moles B) No. of moles = given no. of particles/avagardo no. = 6.022 X 10^22 / 12.044 x 10^22 = 2 moles
