Anna is free-diving many metres below the surface. At her current depth, the water pressure is 1860 mmHg. Using Boyle’s law p = k/V, calculate the volume of Jane’s lungs (in litres) at that depth, using k=1000. Round your answer to two decimal places (for example, a value of 8.545 becomes 8.55 whereas a value of 8.544 rounded to two decimal places is 8.54).
