Solid PbBr2 (Ksp = 6.6 x 10-6) added to a solution of AgNO3, which results in the formation of solid AgBr (Ksp =5.5 x 10-13). For the following question, enter your answer to the appropriate number of significant figures. When inputting an answer in scientific notation, use “e” notation rather than multiplying by a power of 10. For example: 0.00031 = 3.1e-4. Do not write 3.2x10^-4. Do not include units in your answer (but do consider them when solving the problem!)

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
