Answer:
The lens with 4x magnification or the lowest power objective
Explanation:
When you use the low power objective, you have a wider field of view. This would make locating the specimen a lot easier than it would be if you used one with a higher magnification. Once you focus the microscope using the low power objective, you can switch to the higher magnification lenses.
We calculate the number of moles of water given its mass by dividing the mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2
