Answer
The density of the orange juice is approximately 1156 kg/m³.
Explanation
## Step1: Convert the volume from cm³ to m³.Remember, 1 cm³ =
m³.Therefore, 320 cm³ =
0.00032 m³.## Step2: Convert the mass from grams to kilograms.Remember, 1 g =
kg.Therefore, 370 g =
0.37 kg.## Step3: With the mass and volume now in the appropriate units, we can use the density formula.### The density formula is
.In this case, Density =
rounding to the nearest integer. So, the density of the juice is approximately 1156 kg/m³.
