Answer:
9.15 × 10²³ molecules of N₂O present.
Explanation:
Given data:
number of moles = 1.52 mol
molar mass of N₂O = 44.013 g/mol
number of molecules = ?
Solution:
First of all we will calculate the mass of 1.52 mol.
mass = number of moles × molar mass
mass = 1.52 × 44.013 g/mol
mass = 66.9 g
Now we will find the number of molecules by using Avogadro number,
The number 6.022×10∧23 is called Avogadro number and it is the number of atoms or molecule in one gram atom of an element or one gram molecule of a compound.
44.013 g of N₂O = one mole of N₂O= 6.02 × 10²³ molecules
For 66.9 g:
66.9 g/ 44.013 g × 6.02 × 10²³ molecules
9.15 × 10²³ molecules of N₂O present
Answer:
4. K = [CF₂Cl₂] [HCl]² / [HF]² [CCl₄]
5. K = [NH₃] [HCl]
6. K = 1 / [SO₃]
Explanation:
Equilibrium constant expressions are defined as the ratio between concentrations of products and concentrations of reactants powered to its reaction quotient (Compounds in solid or liquid phase are not taken in the expression).
For the reactions:
4. CCl₄(g) + 2HF(g) ⇌ CF₂Cl₂(g) + 2HCl(g)
Equilibrium expression, K, is:
<em>K = [CF₂Cl₂] [HCl]² / [HF]² [CCl₄]</em>
5. NH₄Cl(s) ⇌ NH₃(g) + HCl(g)
<em>K = [NH₃] [HCl]</em>
6. SO₃(g) + H₂O(l) ⇌ H₂SO₄(l)
<em>K = 1 / [SO₃]</em>
