An empty flask has a mass of 123.4 g. when the flask is filled with water, the madd is 211.6g. if 10.0g of zinc (d=7.14 g/cm^3) are added to the flask filled with water (and the sides of the flask are dried from the displaced water) what is the new volume in the flask? (hint: you are going to have to use the density of water to answer this question)

- 89.6 mL

Solution:- Mass of empty flask = 123.4 g

mass of flask filled with water = 211.6 g

So, mass of water in the flask = 211.6 g - 123.4 g = 88.2 g

we know that density of water is .

So, volume of water in the flask =

= 88.2 mL

Mass and density is also given for Zn metal. So, we could calculate the volume of metal also using the same formula used for water.

volume of Zn =

= 1.40 mL

New volume of the flask would be the sum of the volumes of water and metal.

So, new volume of the flask = 88.2 mL + 1.40 mL = 89.6 mL

Hence, the new volume of the flask after adding the metal to it is 89.6 mL.

hey your not cool]      

the answer to this question is 3.
