Theoretical yield:
02 -> H2O
1mol -> 2mol
2mol -> 4mol
32g -> 72g
Theoretical yield = 72g
Percent yield = actual yield/theoretical yield * 100
= 33.1/72 *100
=45.97%

Answer:
1 × 10⁻² M
Explanation:
<em>What is the [H₃O⁺] in a solution with [OH⁻] = 1 × 10⁻¹² M?</em>
Step 1: Given data
Hydroxile ion concentration ([OH⁻]): 1 × 10⁻¹² M
Step 2: Calculate the concentration of the hydronium ion
Let's consider the self-dissociation of water.
2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)
We can calculate the concentration of the hydronium ion using the ion product of water.
Kw = 10⁻¹⁴ = [H₃O⁺] [OH⁻]
[H₃O⁺] = 10⁻¹⁴ / [OH⁻] = 10⁻¹⁴ / 1 × 10⁻¹² = 1 × 10⁻² M
Answer:
Destiny = 5 g/ml
Explanation:
The formula for density is d=
Knowing this, divide your mass by volume:
10 g / 2 ml = 5 g/ml
Final answer:
Destiny = 5 g/ml
Answer:
0.125 M
Explanation:
Initial volume = 300 mL
Final Volume = 300+300 = 600 mL
Initial Molarity = 0.25 M
Since the same amount of water is added to the sulfuric acid the molarity will be halved.
The above result can be elaborated by the following steps
So, the new Molarity is 0.125 M
