Compound has a molar mass of and the following composition: element mass % carbon 58.77% hydrogen 13.81% nitrogen 27.42% Write the molecular formula of .

C5H14N2

Explanation:

The element mass are:

C = 58.77 g

H = 13.81 g

N = 27.42 g

To get their moles, we have to divide by the molar mass which will be:

C: 58.77 / 12.01 = 4.8934

H: 13.81 / 1.008 = 13.7004

N: 27.42 / 14.01 = 1.9572

We then divide by the smallest mole which will be:

C: 4.8934 / 1.9572 = 2.5

H: 13.7004 / 1.9572 = 7

N: 1.9572 / 1.9572 = 1

We then multiply by 2 so that we can get whole number ratio:

C: 2.5 × 2 = 5

H: 7 × 2 = 14

N: 1 × 2 = 2

Therefore, the empirical formula will be = C5H14N2

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

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.
