What is the atomic weight of the element? Calculate the number of oxygen atoms in a 150.0 g sample of forsterite (Mg2SiO4). One isotope has an abundance of 57.3% and an isotopic mass of 120.904 amu. Based on these data, what is the mass of the other isotope? A 130.2 gram sample of an unknown substance MM = 189.50 g/mol is cooled from When two equal charges q1 and q2 are separated by a distance r, the repulsive force between the
