Question

Растительное масло объёмом 1 л имеет массу 920 г. Найдите плотность масла, выразите её в кг на см в кубе

Answer 1

плотност=m/V

плотност=0.92/0.001=920 кг/м^3 

Answer 2

920 г* 0,001 кг=0,92 кг*1см3=0,92кг/см3

Answer 3

Calculation of Density

To find the density of the vegetable oil, we can use the formula:

Density (ρ) = Mass (m) / Volume (V)

Given that the mass of the vegetable oil is 920 g and the volume is 1 L, we can substitute these values into the formula:

Density (ρ) = 920 g / 1 L

However, we need to convert the mass from grams to kilograms and the volume from liters to cubic centimeters (cm³) to express the density in kg/cm³.

1 kg = 1000 g 1 L = 1000 cm³

Converting the mass and volume:

Density (ρ) = 0.92 kg / 1000 cm³

Simplifying the expression:

Density (ρ) = 0.00092 kg/cm³

Therefore, the density of the vegetable oil is 0.00092 kg/cm³.
