Question

2. En el sobre de un jugo instantáneo aparece la siguiente información: “prepare un delicioso litro de jugo de naranja”. Si con el litro de jugo se llenaron 5 vasos, ¿Cuál es la capacidad de cada vaso en mililitros?

3. Consultar sobre unidades de masa y un ejemplo

Answer 1

2) 200 mL

3) 0.2 kg

Explanation:

2)

In this problem, we know that:

- With 1 liter of juice, we can fill a total of 5 cups

So we know that the total volume of 5 cups is equal to

V = 1 L

This means that the volume of each cup is equal to the total volume divided by the number of cups (5), therefore:

`V_1=(V)/(5)=(1L)/(5)=0.2 L`

And keeping in mind the equivalence between liters and milliliters:

1 L = 1000 mL

This means that the capacity of each cup is

`V_1=0.2 L \cdot 1000 mL/L = 200 mL`

3)

Here we want to find the mass contained in each cup.

We know that the mass of a substance is related to each volume by the equation

`d=(m)/(V)`

where

d is the density

m is the mass

V is the volume

In this problem, we have:

V = 0.2 L is the volume of juice in each cup

`d=1kg/L` is the density of juice (assuming it is the same as the density of water)

So, the mass of juice in one cup is:

`m=dV=(1)(0.2)=0.2 kg`
