Question

Determino la masa en gramos y kilogramos de 1500 cm3 de alcohol etílico, cuya densidad es aproximadamente 790.0 Kg/m3. Tomar en cuenta que: Densidad (ρ) = masa (m)/volumen(v).

Answer 1

Para calcular el contenido en gramos de una bebida alcohólica basta con multiplicar los grados de la misma por la densidad del alcohol (0,8). El contenido de alcohol de una bebida depende de la concentración de alcohol y del volumen contenido.

Answer 2

The mass in grams and in kilograms of ethyl alcohol respectively is: a) 1185.0 g and b) 1185 kg

What is density?

Density is an intensive property of matter. It represents the relationship between the mass and the volume of a body or substance. Its units are in the International System kg/m3, kg/L, g/ml, g/cm3, among others.

The density formula is:

Density = m/V

The mass is obtained by clearing this equation

m=Density *Volume

data

m= ?

V= 1500 cm3 * 1 * 10⁻⁶ m³ / 1 cm³ = 0.0015 m³ = 1.5 * 10⁻³ m₃

Density= 790.0 kg/m3

m = 790.0 kg/m³ * 1.5 * 10⁻³m³ = 1.185 Kg

m = 1.185 kg * 1000 g/ 1 kg = 1185,0 g

m=  1185,0 g
