Be sure to answer all parts. an empty erlenmeyer flask weighs 254.0 g. when filled with water (d = 1.00 g/cm3), the flask and its contents weigh 406.9 g. (a) what is the volume of water in the flask? enter your answer in scientific notation.

Solution:

The initial mass of flask is 254 g, mass of flask when water added is 406.9 g thus mass of water will be difference of final and initial mass.

m=406.9 g-254 g=152.9 g

The density of water is 1.00 g/cm^{3}

volume can be calculated as follows:

V=\frac{m}{d}

Here, m is mass and d is density.

Putting the values,

V=\frac{152.9 g}{1.00 g/cm^{3}}=152.9 cm^{3}

In scientific notation, the volume of water in the flask will be 1.529\times 10^{2} cm^{3}.
