120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)

i think u put 2 before NO3
Explanation:
<span>If we dissolve 25 grams of salt in 251 grams of water, then the mass of the resulting solution would be 276 grams. This is in accordance to the Law of Conservation of mass which states that mass cannot be created or destroyed. So, the total mass that goes in a certain process should be the same that would would go out the process. In this case, we have two streams that goes in and one stream going out which would be the solution. The two streams going in should be equal to the stream going out.
Overall mass balance:
25 grams salt + 251 grams water = mass of solution
mass of solution = 276 grams</span>
