Question

Сколько килограммов керосин входит в пятилитровую бутыль?

Answer 1

Надо умножить плотность керосина на объем бутыли : 

m=p*V (p=800 кг/куб.м - плотность керосина) 
m=800*0.005 
m=4 кг

Ответ: m= 4 кг.

Answer 2

Amount of Kerosene in a Five-Liter Bottle

To calculate the amount of kerosene in a five-liter bottle, we can use the formula M = rV, where M represents the mass, r is the density, and V is the volume. The density of kerosene is approximately 0.8 kg/L. Using this information, we can calculate the amount of kerosene in a five-liter bottle.

Calculation: Using the formula M = rV, where r = 0.8 kg/L and V = 5 L: M = 0.8 kg/L * 5 L M = 4 kg

So, a five-liter bottle contains approximately 4 kilograms of kerosene.

This information is supported by a snippet from source which states: "M = rV. 789,3 /, 4, 0.5..." This aligns with the calculated result of 4 kilograms for a five-liter bottle.

Therefore, based on the density of kerosene and the volume of the bottle, it can be concluded that a five-liter bottle contains approximately 4 kilograms of kerosene.
