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

1. 46593.6g

2. 177065.856g

Explanation:

1. 13.6*3426=46593.6g

2. = * 3.14=452.16 (area of circle)

452.16*44.0=19895.04 (volume of cylinder)

8.90*19895.04=177065.856g

≈177065.9g

Hope this helps.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
