Presentation Transcript

  1. Split page into 6 sections and label as follows:

  2. What is molar Mass? • Molar Mass: the mass of one mole of an element or compound; a mole is a unit of measurement in chemistry used to tell the amount of something • Compound? • The molar mass of a compound is obtained by summing the masses of the component atoms. (the mass of each atom is the decimal number found on the periodic table)

  3. What is the molar mass of CH4?

  4. Calculate the Molar Mass of the following: • Calcium Phosphate: • What is calcium phosphate’s formula? • Ca3(PO4)2 • How many of each element are in the compound and what are the masses of each element? Ca: 3 * 40.078 = 120.234 P: 2 * 30.9738 = 61.9476 O: 8 * 15.9994 = 127.9952 TOTAL: = 310.1768 g/mol When you are asked to show your work when finding the molar mass, the above is what I need to see!

  5. % Composition  how much of each compound is made up of a particular element 5 mass of element mass of compound % element = x 100

  6. Calculate the % composition of each element in cobalt (II) phosphate Formula: ________________ % Co: __________ Molar Mass: ______________ % P: ___________ % O: ___________ Mass of Co: ____________ Mass of P: _____________ Mass of O: _____________
