Igot a few questions 1.are we alone in the universe? 2.what makes us human 3.what is consciousness? 4. why do we dream? 5.how do we get more energy from the sun? need asap

1. We don't know yet, but personally I think there are "aliens" in the universe

2. Humans communicate with a very complex language plus we're not crazy like animals

3. the state of being aware

4. I think we dream so the brain can sort out all of our memories throughout the day.

5. The sun gives us many different types of vitamins through our skin.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
