Mixing bleach with rubbing alcohol and/or hydrogen peroxide can run the risk of producing chlorine gas. This is a gas that if inhaled in excess, or at all, is extremely dangerous, harmful or even fatal. Keeping this in mind, it is therefore not recommended that you mix these substances together. The label of your rubbing alcohol will recommend any substances it can or cannot be mixed with.
Answer:
The correct answer is 10.939 mol ≅ 10.94 mol
Explanation:
According to Avogadro's gases law, the number of moles of an ideal gas (n) at constant pressure and temperature, is directly proportional to the volume (V).
For the initial gas (1), we have:
n₁= 1.59 mol
V₁= 641 mL= 0.641 L
For the final gas (2), we have:
V₂: 4.41 L
The relation between 1 and 2 is given by:
n₁/V₁ = n₂/V₂
We calculate n₂ as follows:
n₂= (n₁/V₁) x V₂ = (1.59 mol/0.641 L) x 4.41 L = 10.939 mol ≅ 10.94 mol
