<span>(15.0 g) / (150.0 g) x (100 g) = 10.0 g/100 g H2O </span>
Answer:
See explanation
Explanation:
The mole refers to the amount of substance contained in 12 g of carbon-12. It was arbitrarily related to the number of elementary entities in 12 g of carbon -12 by Prof. Avogadro.
The number of moles of a substance is obtained as the mass of the substance divided by the mass of one mole of the substance (molar mass). Hence when the number of moles is known, the mass is now;
number of moles * molar mass
Answer: N-N: 145 pm and 167 KJ/mol
N=N: 125 pm, 418 KJ/mol
And N2: 110 pm , 942 KJ/mol
Explanation: Bond length is inversily proportional to bond energy.
Greater the bond length , smaller the bond energy and vice-versa.
