  1. QUIZ

  2. Q1 • What is the formula weight(Molecular weight) for C6H6.(BENZENE) • SHOW YOUR WORK

  3. Q2 How many atoms are in 100gof Benzene (C6H6) SHOW YOUR WORK

  4. Q1 • What is the formula weight(Molecular weight) for C6H6.(BENZENE) Molar mass Moles C= (12g/mol X 6)= 72g H= (1g/mol X 6)= 6g 1mol of C6H6= 78g • SHOW YOUR WORK 1 pt for each scribbled box 1 pt for units

  5. Q2.How many atoms are in 100g of Benzene (C6H5) 100g-> ? Atoms we know: 1 mol=6.022X10^23 1 mole= 78g) 100 g Benzene 6.022 x 1023 atoms bezene 1 molBenzene 78 g Benzene 1 molBenzene 7.72 x 1023 (100)(6.022 x 1023)/78 = atoms Benzene 1 pt for each scribbled box 1 pt for units 1 pt for DATE AND NAME 10 pt total
