Butter has a specific gravity of 0.86. what is the mass of 2.15 l of butter?

The mass of butter is 1849 g.

Explanation:

Given data:

Specific gravity of butter = 0.86

Volume = 2.15 L

Mass = ?

Solution:

Specific gravity of a substance is the ratio of density of substance divided by the density of water.

Thus the density of butter is 0.86 g/mL

Formula:

Conversion from L to mL

2.15 /1000 = 2150 mL

d = m/v

0.86 g/mL = m/2150 mL

m =  1849 g

Thus the mass of butter is 1849 g.

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.
