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.

Answer: The percentages of carbon and hydrogen numerically to four significant figures is 
and 
respectively.
Explanation:
Molar mass of the compound is the mass of 1 mole of compound which is the sum of masses of each element.
Mass of 1 mole of compound= mass of carbon + mass of hydrogen+ = 5(12) + 12(1)= 72 g.
a) Percentage by mass of carbon =
Percentage by mass of carbon =
b) Percentage by mass of hydrogen =
Percentage by mass of hydrogen =
