Answer:
x = 33.52 amu
Explanation:
It is given that,
Isotope A has a mass of 34 amu and an abundance of 52%, isotope B has a mass of 33 amu and an abundance of 48%.
Let x is the average atomic mass of this element. It can be calculated as follows :
So, the average atomic mass of this element is 33.52 amu.

Answer:
The approximate molar mass of NaOH is 40 g/mol. You have 4 g NaOH.
No. of moles of NaOH is given by
n=(Given mass)/(Molar mass)
= 4/40 = 0.1 mol
1 mol has 6.022 × 10^23 molecules.
Thus, 0.1 mol has 6.022 × 10^23 × 0.1 molecules i.e. 6.022 × 10^22 molecules.
