Question

what is the mass of 0.2 mole of number of particals in 23 grams of na atom
atomic mass of na=32u​

Answer 1

Answer:

8dyixkztktoz6(5*6/")6)6$6)*5(*(6"(6"(*5"6))6"")77)")"7*)6

Answer 2

Answer:

4.6 gms.

Explanation:

There are 6.02*10^23 atoms in each mole (Avagadro no.) That is x moles * avagadro no. According to that, in 23 grams of sodium we have 6.02*10^23 atoms of Na.

Atomic Mass of Na is 23 u.

so, the required mass of Number of particles in 23 gms = 0.2 × 23 = 4.6 g.
