Question

1. 0.35 m = ______ μm measurement =
2. 25 cg = ______ g measurement =
3. 400 mg = ______ kg (hint: 2 prefixes will need 2 conversions) measurement =
4. 30 cm = ______ mm measurement =
5. 0.156 ms = ______ s measurement =
6. 15 m = ______ dm measurement =
7. 0.75 l = ______ ml measurement =
8. 6.4 kg = ______ g measurement =
9. 7200 mol = ______ cmol measurement =
10. 4.2 l = ______ cm³ measurement =

Explanation:

Step1: Recall metric - prefix conversion factors

1 m = 10^6 μm.

Step2: Convert 0.35 m to μm

0.35×10^6 = 350000 μm.

Step3: Recall centi - to - gram conversion

1 g = 100 cg, so 25 cg = 25÷100 = 0.25 g.

Step4: Recall milligram - to - kilogram conversion

1 kg = 1000000 mg, so 400 mg = 400÷1000000 = 0.0004 kg.

Step5: Recall centimeter - to - millimeter conversion

1 cm = 10 mm, so 30 cm = 30×10 = 300 mm.

Step6: Recall mega - to - second conversion

1 Ms = 10^6 s, so 0.156 Ms = 0.156×10^6 = 156000 s.

Step7: Recall meter - to - decimeter conversion

1 m = 10 dm, so 15 m = 15×10 = 150 dm.

Step8: Recall liter - to - milliliter conversion

1 L = 1000 mL, so 0.75 L = 0.75×1000 = 750 mL.

Step9: Recall kilogram - to - gram conversion

1 kg = 1000 g, so 6.4 kg = 6.4×1000 = 6400 g.

Step10: Recall mole - to - centimole conversion

1 mol = 100 cmol, so 7200 mol = 7200×100 = 720000 cmol.

Step11: Recall liter - to - cubic - centimeter conversion

1 L = 1000 cm^3, so 4.2 L = 4.2×1000 = 4200 cm^3.
