Answer:
Four significant figures.
Explanation:
Hello,
In this case, considering that the measurement 16.08 L has four digits we must take into account that all are significant even the zero due to fact that is to the right of the first nonzero digit which is 1, therefore, the measurement has four significant figures.

The number of molecules of water is calculated as follows
find the moles of water= moles=mass/molar mass
moles = 69.1g/18 g/mol = 3.84 moles
by use of Avogadro law constant
that is 1 mole = 6.02 x10^23 molecules what about 3.84 moles of water
the molecules of water = (3.84 x 6.02 x10^23) = 2.312 x10^24 molecules
Answer:
Emission spectra may be used in studying stars in order to determine what atoms makeup the individual star produces, due to the fact that each atom’s emission spectra biunique, one can observe the spectra emitted by the star and identify the atoms that are released by the light the star produces.
