Recall that a mole is defined as Avogadro's number of particles what the formula of caffeine basically tells us is that every molecule of caffeine you will have 8 atoms of carbon 10 atoms of hydrogen 4 atoms of nitrogen and 2 atoms of oxygen so if we have 0.3 moles of caffeine we will have 4*0.3 moles of nitrogen which is 0.12 and you got the idea
Answer:
1.5 litre of C5H12 produce 9 litre of water vapour;
Explanation:
First balance the combustion reaction;
→ 
from the balance reacion it is clearly that,
one mole of C5H12 reacts completely with 8 mole of O2 gas;
Hence
one litre of C5H12 reacts completely with 8 litre of O2 gas;
there fore 1.5 litre C5H12 needs 12 litre oxygen gas but we have 15 litre.
so,
C5H12 is a limiing reactant and O2 is a excess reactant.
so quantity of H2O depends on limiting reactant;
one litre of C5H12 produce 6 litre of water vapour;
therefore,
1.5 litre of C5H12 produce 9 litre of water vapour;
The correct response would be C. Those in the outermost shell, and of highest electron energy are the valence electrons for potassium.
Answer:
Phosphate possess ATP molecule which provides energy to the DNA or RNA molecule for the movement of the nucleus
Explanation:
Along with the Nucleic acids , bases , phosphate molecules bonds with the 4 oxygen atoms in the structure . it has real importance in the DNA structure for providing the energy of ATP to the molecule
