Answer 1

1.55 g/L; 9.503 03 × 10^20 mL

Part 1.

Step 1. Convert kilograms to grams.

1.55 kg × (1000 g/1 kg) = 1550 g

Step 2. Convert cubic metres to litres.

1 m^3 × (1000 L/1 m^3) = 1000 L

Step 3. Divide grams by litres

1.55 kg/1 m^3 = 1550 g/1000 L =  1.55 g/L

Part 2.

Step 1. Convert cubic kilometres  to cubic metres

950 303 km^3 × (1000 m/1 km)^3 = 9.503 03 × 10^14 m^3

Step 2. Convert cubic metres to litres.

9.503 03 × 10^14 m^3 × (1000 L/1 m^3) =  9.503 03 × 10^17 L

Step 3. Convert litres to millilitres.

9.503 03 × 10^17 L × (1000 mL/1 mL) = 9.503 03 × 10^20 mL
