Questions: 5. Convert 4.5 μg (micrograms) to grams. 4.5 × 10^-6 g 6. Convert 3 mL to μL (microliters). 3000 7. Convert 80 μL (microliters) to milliliters. 0.08 8. Convert 0.8 mL to μL (microliters). 800

Solution Steps

• Understand that \(1 \, \mu \mathrm{g} = 10^{-6} \, \mathrm{g}\).
• Multiply \(4.5 \, \mu \mathrm{g}\) by \(10^{-6}\) to convert to grams.
• Calculation: \(4.5 \times 10^{-6} \, \mathrm{g}\).

• Recognize that \(1 \, \mathrm{mL} = 1000 \, \mu \mathrm{L}\).
• Multiply \(3 \, \mathrm{mL}\) by \(1000\) to convert to microliters.
• Calculation: \(3 \times 1000 = 3000 \, \mu \mathrm{L}\).

• Know that \(1 \, \mathrm{mL} = 1000 \, \mu \mathrm{L}\).
• Divide \(80 \, \mu \mathrm{L}\) by \(1000\) to convert to milliliters.
• Calculation: \(\frac{80}{1000} = 0.08 \, \mathrm{mL}\).
