Question

Найдите массу керосина в конистре объемом 5 л.

Answer 1

Масса равно плотность умножить на объем, по таблице смотрим, плотность керосина 800 кг на метр в кубе, объем переводим 5 литров= 0,005 метра кубических. Получаем, масса равна 800*0,005=4 кг.
Ответ: m=4 кг.

Answer 2

Calculating the Mass of Kerosene in a 5L Container

To calculate the mass of kerosene in a 5L container, we can use the formula m = ρV, where m is the mass, ρ is the density, and V is the volume.

Using the provided information, we can calculate the mass of kerosene in the 5L container.

1. Density Calculation: - The density of kerosene is given as 800 g/L in the provided information.

2. Mass Calculation: - Using the formula m = ρV, where m is the mass, ρ is the density, and V is the volume, we can calculate the mass of kerosene in the 5L container.

- Substituting the values: - ρ = 800 g/L - V = 5 L

We get: - m = 800 g/L * 5 L = 4000 g = 4 kg.

3. Final Result: - Therefore, the mass of kerosene in the 5L container is 4 kilograms.

So, the mass of kerosene in a 5L container is 4 kilograms.
