A mixture is made by combining 1.17 lb of salt and 3.54lb of water. What is the percentage of salt (by mass) in this mixture?

The percentage of salt in the mixture 24.84%

Explanation:

In this problem we are required to solve for the percentage of salt in the mixture of salt and water

Step one :

We can proceed by first solving for the total mass of the mixture

Which is given as

mass of mixture =mass of salt +mass of water

Mass of mixture = 1.17+3.54

Mass of mixture = 4.71 lb

Step two :

Now let us calculate the percentage of salt present in the mixture which is

=(mass of salt/mass of mixture) *100

=(1.17/4.71)*100

=0.248*100

=24.84%

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
