### Question 1 **Which is smallest?** - ⃝ 25 g - ⃝ 250 mg - ⃝ 0.0025 kg - ⃝ 2500 mcg --- #### Explanation: This question tests your understanding of different units of mass (weight) and how to convert between them. Here are the conversions needed to compare these values: 1. **25 g** (grams) 2. **250 mg** (milligrams) - \(250 \text{ mg} = 0.25 \text{ g}\) (since 1 g = 1000 mg) 3. **0.0025 kg** (kilograms) - \(0.0025 \text{ kg} = 2.5 \text{ g}\) (since 1 kg = 1000 g) 4. **2500 mcg** (micrograms) - \(2500 \text{ mcg} = 0.0025 \text{ g}\) (since 1 g = 1,000,000 mcg) After conversion to grams, we have: - 25 g - 0.25 g - 2.5 g - 0.0025 g The smallest value is **2500 mcg, which equals 0.0025 grams.**
