Calculate the no of atoms present in 46 g of na atom

1.	Calculate the no of atoms present in 46 g of na atom
Answer» ANSWER: No of MOLES of Na = mass of Sodium/MOLAR mass 1) FRIST we have to divide mass of Na w.r.t molar mass of Na #) molar mass of Na =23 gm/mol #) no of moles of Na =46/23 =2mol 2) than we easily get the no of moless. no of atoms in Na =2 * avocadro no= 2 * 6.03 10^23 =12.06 10^23 atom 3) than we have to multiply the no of moless wd avocadro no.

Answer»

ANSWER:

No of MOLES of Na = mass of Sodium/MOLAR mass

1) FRIST we have to divide mass of Na w.r.t molar mass of Na

#) molar mass of Na =23 gm/mol

#) no of moles of Na =46/23

=2mol

2) than we easily get the no of moless.

no of atoms in Na =2 * avocadro no= 2 * 6.03 *10^23 =12.06 *10^23 atom

3) than we have to multiply the no of moless wd avocadro no.
