If the specific gravity of pineapple juice is 1.40 what mass 1 Liter in kilograms?

- Specific gravity of pineapple juice (SG) = 1.40

- Volume of pineapple juice (V) = 1 Liter

To Find:

- Mass of pineapple juice (m) in kilograms (kg)

Solution:

The specific gravity (SG) is defined as the ratio of the density of a substance to the density of water at 4°C. In this case, the specific gravity of pineapple juice is 1.40, which means that pineapple juice is 1.40 times denser than water.

The density of water at 4°C is 1000 kg/m³. Since the specific gravity of pineapple juice is 1.40, the density of pineapple juice (ρ) can be calculated as follows:

ρ = SG × ρwater

ρ = 1.40 × 1000 kg/m³

ρ = 1400 kg/m³

Now, we can calculate the mass (m) of 1 Liter (0.001 m³) of pineapple juice using the formula:

m = ρ × V

m = 1400 kg/m³ × 0.001 m³

m = 1.4 kg

Therefore, the mass of 1 Liter of pineapple juice is 1.4 kilograms.
