  3. 2. .00000093 Tg = g This is just a metric conversion ---- always 2 steps. One step to the BASE unit, grams: One step to the desired unit, micrograms: Start with what you’re given: 1 g 1x1012 g .00000093Tg x x 1 Tg 1x10-6 g 9.3x1011g

  4. 3. 8.5 x 10-20 Ml = ml This is just a metric conversion ---- always 2 steps. One step to the BASE unit, liters: One step to the desired unit, milliliters: Start with what you’re given: 1 ml 1x106 l 8.5 x10-20 Ml x x 1 Ml 1x10-3 l 1000 ml 1 l Or you could use this for last fraction  8.5x10-11 ml

  5. 4. 8 gallons = liters Gallons is an English unit and liters is a metric unit - determine what Metric-English conversion will work (from box at top of homework) Start with what you’re given: 4 .94 l qt 8 gal x x 1 gal 1 qt 1 sig fig 30.08 liters 30 liters
