Question

calculate the number of sodium atoms
in 14g of Na2So4



​

Answer 1

Answer:

Step-by-step explanation:

there are 2 sodium (Na)

Answer 2

Answer:

given mass = 14g

molecular mass = 142 amu

moles = 14/142

W.K;

moles = avagadro number/number of atoms

14/142 = 6.022*10^-23*number of atoms

Hence atoms = 14/142*6.022*10^-23
