(a) The dilution equation can be used, appropriately modified to accommodate mass-based concentration units: %mass1 × mass1 = %mass2 × mass2 % mass 1 × mass 1 = % mass 2 × mass 2. This equation can be rearranged to isolate mass 1 and the given quantities substituted into this equation. (b) 58.8 g. Math Rule 1. Measured data must be the same kind of dimension and gave the same units before they can be added or subtracted. Math Rule 2.

Light and other forms of electromagnetic radiation move through a vacuum with a constant speed, c, of 2.998 × × 10 8 m s −1. This radiation shows wavelike behavior, which can be characterized by a frequency, ν, and a wavelength, λ, such that c = λν. Light is an example of a travelling wave.Dalton's Atomic Theory (Part 3) Atoms cannot be subdivided, created, or destroyed.
