Understand that the problem is asking for the approximate percentage of water by mass in a typical human cell.
Recall that human cells are composed largely of water, which acts as a solvent and medium for biochemical reactions.
Remember that water typically makes up the majority of the mass in most cells, often around two-thirds to three-quarters of the total mass.
Use this biological knowledge to estimate that the percentage of water in a typical human cell is close to 70%.
Confirm that this estimate aligns with standard cell biology references stating that about 70% of a human cell's mass is water.
