Answer:
Mass percent = (mass of chemical/total mass of compound) x 100 = (5 g/105 g) x 100. (5/105) x 100 = 0.04761 x 100 = 4.761%.
the mass fraction of a substance within a mixture is the ratio w_{i} of the mass m_{i} of that substance to the total mass {\displaystyle m_{\text{tot}}} of the mixture.
