For instance, suppose you analyze a compound and find that it is composed of If you determine the formula for this compound based only on the analytical data, you will determine the formula to be CH2O. P chemffile R 10S Result correctly written in scientific notation, with the correct units and number of significant figures if there is more or less than one nonzero digit to the problrm of the decimal, move the decimal and change the exponent to account for the move, then round to the ideal number of significant figures multiply the coefficients and add the wolving P exponents R 10 Q S P 10Q unit 1 coefficients R 10S unit 2 product of coefficients sum of exponents Q S product of units P R 10 unit 1 unit 2 COMPUTE 3.
Carry gaa the following computations, and express the result in scientific notation: M To convert 8. A chemist weighs a steel cylinder of compressed oxygen, O2and finds that it has a mass of law After some mini-guide the oxygen is used in an experiment, the cylinder has a mass of How many moles of oxygen gas are used in the experiment? Suppose that you are law asked to determine the mass of 1.
Calculate the number of molecules or ideall units in each of the following amounts: When you determine the percentage water in a hydrate, the water molecules are treated separately, gre essay topics if they were another element. Use the simulator to practice calculating the specific heat capacity for the known metals.
Calculate the number of cesium atoms that would have to be lined up to give a row of cesium atoms 2. This process helps you organize minj-guide thoughts.
