Pi is an irrational number -- a number with an unending string of non-repeating digits after the decimal point. While it has been calculated to more than 10 trillion places, most of the time just a few decimal places will do. We'll look at two different ways to calculate pi: By measuring a circle and by solving a ... 2.1.3 (h) calculations to determine: (i) the percentage yield of a reaction or related quantities (ii) the atom economy of a reaction. (i) the techniques and procedures required during experiments requiring the measurement of mass, volumes of solutions and gas volumes.

Mar 06, 2018 · In most applied fields of Chemistry, (w/w) measure is often used, and is commonly expressed as weight-percent concentration, or simply "percent concentration". For example, a solution made by dissolving 10 g of salt with 200 g of water contains "1 part of salt per 20 g of water". Brianna wanted to compare the densities of two different solids of the same size 6cm3 (same volume) to see which one was more dense. Solid A had a mass of 2 grams and Solid B had a mass of 0.5 grams.

You could see this used: "ideal standard gas density." The behavior of "real" gases diverges from predictions based on ideal conditions. Small gases like H 2 at high temperatures approach ideal behavior almost exactly while larger gas molecules (NH 3, for example) at low temperatures diverge the greatest amount.
