Question

Complete each statement.

1. ___kg is the approximate mass of 156 L of water
2.____ kg = 38,000 g
3. ___ mL of water has mass of approximately 1.886 kg
4. _____ m = 5.61 km
5. ____ mg = 0.5 g
6. 0.43 ____ m = cm

Answer 1

To find the mass of 156 L of water, you need to convert liters to milliliters and then multiply by the density of water, which is approximately 1 g/cm³. The conversion factor for grams to kilograms is dividing by 1000. To convert kilometers to meters, multiply by 1000. To convert grams to milligrams, multiply by 1000. To convert meters to centimeters, multiply by 100.

Step-by-step explanation:

1. 564 kg is the approximate mass of 156 L of water. This can be calculated by converting liters to milliliters and then multiplying by the density of water, which is approximately 1 g/cm³. Since 1 g/cm³ is equivalent to 1000 kg/m³, the mass of 1000 mL (or 1 L) of water is 1000 g (or 1 kg). Therefore, the mass of 156 L of water is 156,000 g (or 156 kg).
2. 38 kg = 38,000 g. To convert grams to kilograms, you divide by 1000. Therefore, 38,000 g is equal to 38 kg.
3. The mass of approximately 1.886 kg of water is equal to approximately 1886 mL. This can be calculated by dividing the mass by the density of water, which is approximately 1 g/cm³. Since 1 g/cm³ is equivalent to 1000 kg/m³, the mass of 1000 mL (or 1 L) of water is 1000 g (or 1 kg).
4. 5.61 km = 5610 m. To convert kilometers to meters, you multiply by 1000. Therefore, 5.61 km is equal to 5610 m.
5. 0.5 g = 500 mg. To convert grams to milligrams, you multiply by 1000. Therefore, 0.5 g is equal to 500 mg.
6. 0.43 m = 43 cm. To convert meters to centimeters, you multiply by 100. Therefore, 0.43 m is equal to 43 cm.
