Question

1. What is the density of a gold sample that has a mass of 7.502 g and a volume of 0.051 cm? (Hint: 1 cm3= 1 mL) 2. Mercury has a density of 13.534 g mL1. The Department has a 385 cm container of mercury. What is the mass of the mercury in the container (lbs)? 3. Assume you measure the density of your unknown sample to be 9.1 g/mL The accepted (real) value for the density is 0.082 kg/m. Calculate the percent error in your measured value. Show all working!! For a submarine to dive underwater and then resurface, the crew must be able to control the ship's density. Please, explain how the crew can change the density of the submarine. Feel free to include a picture to aid in your explanation 4.

Explanation / Answer

Solution:-

From the question we have

Mass,m= 7.502 g

and Volume= 0.051 ml^3

So Density= Mass/Volume

= 7.502 g/ 0.051 ml^3

= 147.098 g/ml^3
