Answer:
no of atoms = 13.9 x 10^25
Explanation:
No. of moles = mass of compound / molar mass of compound
As ; mass of sodium = 5.3 x 10^3 g
Molar mass of sodium = 22.9 g/ mol
putting values
n = 5.3 x 10^3 / 22.9
n = 231.4 mol
Also; no of mol (n) = no of particles / Avagadros number
so no of particles = n x Avagadros no.
put n = 231.4 and Avagadros no = 6.023 x 10^23
no of particles = 231.4 x 6.023 x 10^23
= 13.9 x 10^25
18 is 50% of 36
Like 36 divided by 2
Farm water runoff, which causes nitrogen rich fertilizer to be washed into the body of water. The nitrogen feeds the algae bloom.. Hope this helps
