1. Calculate the following: a. Mass of 0.5 mole of oxygen gasb. Number of particles in 24 g of magnesium​

Answer»

tion:3.011 x 1023 atoms of oxygen. (iii) 6.022 x 1024 molecules of oxygen. (Given ATOMIC MASS of 0 = 16u; No = 6.022 x 1023 per mole)1 mole of MgO contains Avogadro's NUMBER of molecules which is 6.023×10 23 molecules.0.5 mole of MgO will contain 0.5×6.023×10 23 =3.0115×10 23 molecules.mark as brilliant
