Math Problem Statement

The density of apple juice is 1.04 grams per cm³. The density of fruit syrup is 1.6 grams per cm³. The density of sparkling water is 0.99 grams per cm³. 35 cm³ of apple juice are mixed with 25 cm³ of fruit syrup and 270 cm³ of sparkling water to make a drink with a volume of 330 cm³. Work out the density of the drink. Give your answer correct to 3 decimal places.

Solution

Let's work through the problem step by step.

Given Data:

  • The density of apple juice is 1.04g/cm31.04 \, \text{g/cm}^3.

  • The density of fruit syrup is 1.6g/cm31.6 \, \text{g/cm}^3.

  • The density of sparkling water is 0.99g/cm30.99 \, \text{g/cm}^3.

  • Volume of apple juice: 35cm335 \, \text{cm}^3

  • Volume of fruit syrup: 25cm325 \, \text{cm}^3

  • Volume of sparkling water: 270cm3270 \, \text{cm}^3

Total volume of the mixture: 330cm3330 \, \text{cm}^3

Step 1: Calculate the mass of each component

  1. Mass of apple juice: Mass of apple juice=Density×Volume=1.04×35=36.4g\text{Mass of apple juice} = \text{Density} \times \text{Volume} = 1.04 \times 35 = 36.4 \, \text{g}

  2. Mass of fruit syrup: Mass of fruit syrup=Density×Volume=1.6×25=40g\text{Mass of fruit syrup} = \text{Density} \times \text{Volume} = 1.6 \times 25 = 40 \, \text{g}

  3. Mass of sparkling water: Mass of sparkling water=Density×Volume=0.99×270=267.3g\text{Mass of sparkling water} = \text{Density} \times \text{Volume} = 0.99 \times 270 = 267.3 \, \text{g}

Step 2: Calculate the total mass of the drink

Total mass=36.4+40+267.3=343.7g\text{Total mass} = 36.4 + 40 + 267.3 = 343.7 \, \text{g}

Step 3: Calculate the density of the drink

The density of the drink is given by: Density of the drink=Total massTotal volume=343.73301.041g/cm3\text{Density of the drink} = \frac{\text{Total mass}}{\text{Total volume}} = \frac{343.7}{330} \approx 1.041 \, \text{g/cm}^3

So, the density of the drink is 1.041 g/cm³, correct to three decimal places.

Would you like further details or have any questions?

Relative questions:

  1. How does the density of a mixture relate to the individual densities of its components?
  2. Why is it important to know the density of a drink in real-world scenarios?
  3. What would happen to the density if we increased the amount of fruit syrup?
  4. Can the density of a mixture ever be lower than the lowest density component?
  5. How would you calculate the mass if the density and volume are given but in different units?

Tip:

Always ensure the units are consistent (such as g/cm³) when calculating densities or any related quantities!
