Question

If the density of mercury is 13.6g/ml, what is the mass in grams of 3426 ml of the liquid?
A copper cylinder, 12.0 cm in radius, is 44.9 cm long. If the density of copper is 8.90 g/cm^3, calculate the mass in grans of the cylinder. (Assume pi=3.14

Answer 1

Answer:

1. 46593.6g

2. 177065.856g

Explanation:

1. 13.6*3426=46593.6g

2. $\pi r^{2}$ = $12^{2}$ * 3.14=452.16 $cm^{2}$ (area of circle)

452.16*44.0=19895.04 $cm^{3}$ (volume of cylinder)

8.90*19895.04=177065.856g

≈177065.9g

Hope this helps.
