Can Someone Try To Explain What

Can someone explain this Chemistry problem to me?

P(total) = X1P1 + X2P2,

where X1 and X2 are the mole fractions;
P1 and P2 are the vapor pressures of the pure substances.

NH2NH2CO is 60.06 g/mol.
H2O 18.02 g/mol.

85g NH2NH2CO x (1 mol / 60.06 g) = 1.41 mol NH2NH2CO
150g H2O x ( 1mol / 18.02 g) = 8.324 mol H2O

X(NH2NH2CO) = 1.41 / (1.41 + 8.324) = non volatile
X(H2O) = 8.324 / (1.67 + 8.324) = 0.832

P(total) = (0) + (0.832 x 355) = 295.68

Can someone try to explain this poem to me?

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.



I have to paraphrase it for school and i don't understand what the poem is even about

Could someone please explain what machisomo is?

i have always understood "machismo" to be associated with latino men who are very masculine, but kind of preppy/slightly feminine in a way. you are right in that it is very difficult to describe. and after reading your experience, it seems that it varies from culture to culture. interesting, good luck!

this is how wiki is defining it:

Machismo is a prominently exhibited or excessive masculinity. As an attitude, machismo ranges from a personal sense of virility to a more extreme masculism. In many cultures, machismo is acceptable and even expected.

Can someone try and explain this Chemistry problem to me?

I was wondering if someone could perhaps EXPLAIN how to solve this problem. =]
Assume that element Uus is synthesized and that it has the following isotopes:
284Uus (283.4 amu) 34.60%
285Uus (284.7 amu) 21.20%
288 Uus (287.8 amu) 44.20%
What is the value of the average atomic mass for Uus that would be listed on the periodic table? [please use significant figures]

I don't even know how to begin this problem. x] Thanks to anyone that can help. :]

Could someone try to explain the Big Bang theory in as simple terms as you can?

The big bang theory is our best guess as to how the universe started.

We have discovered that the universe is expanding, like a the surface of a balloon being blown up. So, if we look into the past, it is logical to think that at some point the universe must have been really small, like an empty balloon. Since we don't know what cause the ballooon to expand, we assume there was a huge explosion causing everything to expand.
