Wait, do you mind clarifying what you would like answered for the question?
It speeds up the dissolving of the sugar. Agitation
Answer: 2 mol
Explanation:
- According to the ideal gas law, One mole of an ideal gas at STP (standard temperature and normal pressure) occupies 22.4 liters.
- Using cross multiplication,
1 mol of (O2) → 22.4 L
? → 43.9 L
Therefore, the number of moles of oxygen in 43.9 L = (43.9 × 1)/ 22.4 = 1.96 mol≈ 2 mol..
Answer:
<h2>volume = 3.63 mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
Since we are finding the volume
Making volume the subject we have
<h3>

</h3>
From the question
mass = 63.6 g
Density = 17.5 g/mL
Substitute the values into the above formula and solve for the volume
That's
<h3>

</h3>
We have the final answer as
<h3>volume = 3.63 mL</h3>
Hope this helps you
