Metric Conversions grams (g) is used for mass (weight) liters (l) is used for volume meters (m) is used for distance kilo k hecto h deka dk SI deci centi milli g d c m l m kilo hecto Metric Conversions deka SI deci centi milli We will use a problem solving process called dimensional analysis (tracks). Example 25.0 cg = _______ g 25.0 cg 1 g 100 cg = 0.250 g Example 0.351 hl = _______ ml 0.351 hl 100,000 ml 1 hl = 35,100 ml kilo hecto Metric Conversions deka SI deci centi milli Your turns - convert the following: 15.72 g = ______ mg 15.72 g = _____ kg 15.72 g 1000 mg 1g = 15,720 mg 15.72 g 1 kg 1000g = 0.01572 kg Converting Temperature F = 1.8C + 32 C = (F-32) 1.8 Density = m v D = m/v intensive property density is the same no matter size 50 grams of gold has the same density as 150 grams of gold. Important density to remember water is 1.0 g/ml at 4 oC. Density Problem A substance has a volume of 1.74 ml and a mass of 20.0 grams. What is the density? What is the substance? Use page 96 of your text. Density Problem One more to test your algebra: What is the volume of ice in a container if the density is 0.920 g/ml and the mass is 58.39 g? 0.920 g/ml = 58.39 g V V = 63.5 ml
