Answer:
(4) 266 moles
Explanation:
We have Dinitrogen Pentoxide N2O5
6.41*10^25 molecules are given
No of Moles of N2O5 =
=
= 106.5 mol
Now using Unitary Method
2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5
1 mole of N =
In 106.5 mole of N = = 266.25 mole
So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.
Answer:
<h2>Sodium Chloride (NaCl)</h2>Explanation:
Using the standard solubility table , the solubility of sodium chloride is 36 g/100 mL water at 25°C.
Which means that 1 g of solid(that is in crystal form) sodium chloride will dissolve in 100 mL of water at 25°C.
