The wavelength of light measures the distance between the crests of the wave. Light with a wavelength of \( 635 \mathrm{~nm} \) appears orange. How many \( \mathrm{mm} \) is this? \[ \begin{array}{c} 6.35 \times 10^{-1} \mathrm{~mm} \\ 6.35 \times 10^{2} \mathrm{~mm} \\ 6.35 \times 10^{-4} \mathrm{~mm} \\ 6.35 \times 10^{-7} \mathrm{~mm} \end{array} \] Question 9 The normal calclum level in blood is of \( 3.5 \mathrm{mg} \) per dL. What is the correct conversion factor for this relationship? \( \frac{3400 \mathrm{me}}{1 \mathrm{di}} \) \( \frac{38 \mathrm{me}}{1 \mathrm{~L}} \) \( \frac{1344}{195} \) \( \frac{314 \mathrm{n}}{1 \mathrm{al}} \) A cough medicine has \( 17.5 \% \) active ingredient. If the dose is \( 5 \mathrm{~mL} \), how much of the dose is active ingredient? \[ 3 \times 10^{-1} \mathrm{~mL} \] \( 0.9 \mathrm{~mL} \) \( 3 \times 10^{1} \mathrm{~mL} \) \( 0.875 \mathrm{~mL} \) Question 11 If the dosage for a medication is \( 225 \mathrm{mg} / \mathrm{b} \), how many grams should a \( 25-\mathrm{lb} \) child be given? \[ \begin{array}{l} 5.6 \mathrm{~g} \\ 5.625 \mathrm{~g} \\ 5600 \mathrm{~g} \\ 0.11 \mathrm{~g} \end{array} \] Convert \( 9.40 \mathrm{lbs} \) into \( \mathrm{kg} \). \( 20.7 \mathrm{~kg} \) \( 4.26 \mathrm{bb} \) \( 4.26 \mathrm{~kg} \) \( 4.263 \mathrm{~kg} \) Question 13 \( 0.75 \mathrm{pts} \) A drug advertises that it has \( 18.7 \% \) active ingredient. If the dose is \( 12 \mathrm{~g} \), how much of the dose is active ingredient? 2248 \( 64 \mathrm{~B} \). \( 2.28 \) \( 2.244 \mathrm{~g} \) A metal has a density of \( 3.47 \mathrm{~g} / \mathrm{mL} \). What is the volume in \( \mathrm{mL} \) of \( 15.0 \) grams of this metal? \( 4.32 \mathrm{~mL} \) \( 52.0 \mathrm{~mL} \) \( 0.231 \mathrm{~mL} \) \( 4.3227665076 \mathrm{~mL} \) Match the prefixes with their numerical values using the dropdown. \( 0.001 \) 1000 1000000 \( 0.000001 \) \( 0.01 \) \( 0.000000001 \) State the type of measurement in each of the following statements using the dropdown on the right. I put 12 L of gasoline in my gas tank. I rode my bicycle \( 15 \mathrm{~km} \) today. My dog weighs \( 12 \mathrm{~kg} \). The horse won the race by \( 1.25 \). It is hot today. It is \( 30^{\circ} \mathrm{C} \). My friend is \( 170 \mathrm{~cm} \) tall.
