plz show work so I know how to do

Common Metric Prefixes kilo, k 103 milli, m 10-3 centi, c 10-2 micro, u 106 nano, n pico, p 10-9 10-12 Common conversions 1 lb = 453.6 g 1 mi = 1609 m 1 in = 2.54 cm 1 cm = 1 mL Note: All numeric answers must be given with correct number of significant figs. Unit conversions must use the information given above. 1. Use metric prefixes to express cach of the following without exponents. Example 1.2 x 10-8 m = 12 nm. 3.5 x 10-5 7.1 x 104 L 2. Give the answer with correct sig.figs.: 332.57 +24.668 x 2.38 = 3. The total volume of seawater in a certain body of water is approximately 9.6 x 102' L. If the seawater contains 3.11% salt by mass and the density of seawater is 1.037 g/mL, a) What is the total mass of seawater in the body of water in kg? Show work using the density equation (write the equation) or use dimensional analysis. b) What is the total mass of salt in the seawater in kg? 4. Convert 0.0102 lb/in? (pounds per cubic inch) to mg/mL using dimensional analysis
