Explanation:
It is known that density of water is 1.00 g/ml and it is given that volume of the beaker is 55.0 ml.
As density is mass divided by molar mass.
Mathematically, Density = \(\frac{mass}{volume}\)
Therefore, calculate the mass of water present in the beaker as follows.
Density = \(\frac{mass}{volume}\)
1.00 g/ml = \(\frac{mass}{55.0 ml}\)
mass = \(1.00 g/ml \times 55.0 ml\)
= 55.0 g
Thus, we can conclude that mass of the water is 55.0 g.
