Question

1. Using the experimental data that you collected, show your complete calculations for the empirical formula of the metal oxide that you have formed. (You may complete these by hand. Be sure that all numbers are labeled with the correct units and your math is shown in a logical order down the page.)

2. The identity of the metal can be further determined by calculating the molar mass of the metal. Show your complete calculations. (You may complete these by hand. Be sure that all numbers are labeled with the correct units and your math is shown in a logical order down the page.)

mole of metal: 1.3 * 10^-3

mass of metal: .034g

mass of crucible: 31.551g

mass of metal + crucible: 31.585g

mass of crucible after reaction: 31.605g

mass of oxygen that reacted: .02g

please answer as soon as possible

Answer 1

0 I.. Moles of Metal = 113 xio" = 0.0013 mol. moles of any gen = 0.02 0.00125 99 Let the symbol of metal bem? No. of moles of metal: no. of moles of oxygen bet = 0.0013: 0.00125 = 104T ... The emperical formula of the metal osiede mo 2. 1.3x10 mol. metal = 0.0349 Į mol. metal = 0.0347 = 2615 3x102 : Molar mass of metal = 26115 g/mot.
