The vital capacity will be 4600ml.
<h3>What is
vital capacity?</h3>
The highest amount of air a person can inhale following their maximal exhalation is known as their vital capacity. It is equivalent to the total of the inspiratory, tidal, and expiratory reserve volumes. It roughly corresponds to Forced Vital Capacity. A wet or conventional spirometer can assess a person's vital capacity.
Normal people have a 3 to 5-liter vital capacity.
It enables simultaneous inhalation of the greatest possible volume of clean air and exhalation of the greatest possible volume of stale air. So, by increasing gaseous exchange between the body's various tissues, it improves the amount of energy available for bodily function.
VC = TV₊IRV₊ERV
where,
VC = Vital capacity
TV = Tidal volume
IRV = inspiratory reserve volume
ERV = expiratory reserve volume
VC = 500 ₊ 3000 ₊ 1100
VC = 4600ml
Therefore, the vital capacity will be 4600ml.

It’s Nitrogen (N) with a -3 charge
Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms.
<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms.
</span>
So your answer is 2
Also remember there is a 2 in front of S meaning there are 2 Sulfurs.
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>
<span>Remember the number in front of a element, represents how many atoms there are :)</span>
It is a solution, because it's the alloy of tin and copper
