(B) Water
(C) Oxygen

Please help I’ll mark brainliest!

C

Explanation:

Not only plants release oxygen, also trees do too!

Water is what they need to survive

Carbon Dioxide is what they take in. Hope this helps, have a nice day, and a merry Christmas!

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.
