  1. Notes Sig Figs

  2. RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant

  3. RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant 404= 3(because the zero counts here)

  4. RULES for SIG FIGS • Non-zero digits and zeroes between non-zero digits are always significant 404= 3(because the zero counts here think of a sandwich) 686 = 3 (because all regular numbers except zero…..always count)

  5. Rules for SIG FIGS 2. Leading zeroes are not significant

  6. Rules for SIG FIGS 2. Leading zeroes are not significant 005= 1 sig fig (leading zeroes)

  7. Rules for SIG FIGS 2. Leading zeroes are not significant 005= 1 sig fig (leading zeroes) 0.001 = 1 sig fig (leading zeroes don’t count….start counting when you get to an actual number)

  8. Rules for Sig Figs 3. Zeroes to the right of all non-zero digits are only significant if a decimal point is shown

  9. Rules for Sig Figs 3. Zeroes to the right of all non-zero digits are only significant if a decimal point is shown 0.010 (2 sig figs……because of the Decimal point being there) 10 = 1 sig fig 10. = 2 sig figs

  10. Rules for Sig Figs 4. For values written in scientific notation, the digits in the coefficient are significant 6.82 * 102 = 3 sig figs

  20. Number 5 Write in scientific notation 0.00457 = 4.57 * 10-3

  21. Number 6 Write in scientific notation 4569

  22. Number 6 Write in scientific notation 4569 = 4.569 * 103

  23. Number 7 • Fill in the following for something that has a density of 2.4 g/ml and a volume of 12 ml. D= M= V=

  24. Number 7 • Fill in the following for something that has a density of 2.4 g/ml and a volume of 12 ml. D= 2.4 g/ml M= V=

  25. Number 7 • Fill in the following for something that has a density of 2.4 g/ml and a volume of 12 ml. D= 2.4 g/ml M= V= 12 ml

  26. Number 7 • Fill in the following for something that has a density of 2.4 g/ml and a volume of 12 ml. D= 2.4 g/ml M= V= 12 ml
