Thus, there are 1.47 × 10^(23) molecules present in 122 grams of NO2.
Explanation:
because metal want to give electron and nonmetal want to gain.
The mass of NCl3 in 4.00 moles of NCl3 is 481.44 grams
Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g. The number of particles present in one mole of any substance =Avogadro Number=6.
The formula for number mole is given as:
Number of moles = <u>Mass of the substance </u> ; Now substituting the values
Molar mass
⇒ 4.00 = <u>x </u> [Molar mass of NCl3 = 120.36]
120.36
⇒ x = 4.00 × 120.36
⇒ x = 481.44 grams
Therefore the mass of NCl3 is 481.44 grams
