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
