The correct formula for solving this question is: VC = IRV + ERV + TV, where VC is vital capacity, IRV is inspiratory reserve volume, ERV is expiratory reserve volume and TV is tidal volume. From the given information, TV =500, ERV =1200 and the standard IRV for male is 3100ml, therefore,
VC= 3100 + 1200 + 500 = 4800ml.
The answer to that question is A
You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water. You need to ensure that you use a facemask during the experiment.
<h3>How do we carry out the experiment?</h3>
We know that we require apparatus to carry out a scientific experiment. The apparatus are those things that would help us to carry out the experiment that we want to do.
In this case, the activity is to mix 2 g of sodium bicarbonate with 50 ml of distilled water and then mix the solution. You need a weighing balance to weigh out 2g of solid sodium bicarbonate and a measuring cylinder to measure out 50 mL of water.
