If the density of mercury is 13.6g/ml, what is the mass in grams of 3426 ml of the liquid?

Mass of the mercury liquid=46593.6g

Given:

Density of the mercury liquid=13.6

Volume of the mercury liquid=3426ml

To find:

Mass of the mercury liquid

Step by Step Explanation:

Solution:

As per the formula, density of the liquid is given as

and mass can be derived as

Where, m=mass of the cylinder

=density of the cylinder

v=volume of the cylinder

Given values are  =13.6 and v=3426ml

Substitute these value in the formula we get

m=13.6 \times 3426

m=46593.6g or 46.5936kg

Result:

Thus the mass of mercury liquid is 46593.6g

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
