Question

Complete the following table for the missing ant figure coms, Oxygen gasto ce Baseous particles oxygen (20 points) r e for the missing dimensional analysis for three gaseous part molecules, and ozone (O) molecules. Keep all results with four 5 molecules. Keep all results with four significant Reen Atoms (0) Owygen Gas (0) Oroneo a. Molar Massi/mol) b. How many cas particles present in 0.1000 mol of each? c. The mass of 3.011 410 each gaseous particles (6) d. How many cas particles present in 1.000 grams of each sample? Use the space below to show all your work for each conversion in the rightmost column. 5a.

Answer 1

5 (a)

Molar Mass 0 (Oxygen) Atom : 16 g/mol Oxygen Gas: 32 g/mol Ozone Gas : 48 g/mol

5 (b) Formula to find Number of gas particles = Atomicity X Number of Moles X Avogadro Number

Number of gas bartides in 0.1 mol For Oxyger (o) atom = 1x 0.1 x 6.022x173 particles = 6.022218 particles For oxygen (02) gas = 2x0.1 x 6.022x10 partich = 12.044 x 183 particles For ozone (03) gas= 3x0.1 x 6.022 x 18 a particles = 18.066 x 182 particles

5 (c) To calculate mass, find number of moles and multiply it by molecular mass

Mass of 3.011 x 18% gas particles. oxygen(0) atom = 3.011 X 100 x 16 6.622x1073 For = 8 gram X for oveggen, gas= 3.011 x 18 x 32 = 16 gram ( )° 6.022 XIA? For ozone gas = 3.011 x 10 x 48 = 24 gram 6.022 x 1339 23

5 (d)Formula to find Number of gas particles = Atomicity X Number of Moles X Avogadro Number
