Question

The dunk tank contains 1 KL of h20, after Mr.C falls in, the dunk tank measures 1.25 KI. Mr. C has a mass of 100 Kg. What is Mr. Cs density in g/mL?

Answer 1

Step-by-step explanation

Volume of tank with water = 1 kL

Volume of tank (water + Mr. C) = 1.25 kL

Volume Mr. C = 1.25 kL - 1 kL = 0.25 kL

It is known that 1 kL = 1000 L and 1 L = 1000 mL

So,

0.25 kL x (1000 L/1 kL) x (1000 mL/1 L) = 250000 mL

-----

Now, it is also known that density can be calculated as follows:

`Density\text{ = }(mass)/(volume)`

Therefore,

Density = Mass of Mr. C/Volume of Mr. C

(First, 1 kg = 1000 g, so 100 kg x (1000 g/1 kg) = 100000 g)

----

Density = 100000 g/250000 mL = 0.4 g/mL

Answer: 0.4 g/mL
