GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Mass, Density, Volume - Explained

The video tutorial explains how to calculate the density of a drink made by mixing apple juice, fruit syrup, and carbonated water. It covers the densities of each liquid, the importance of using consistent units, and the method to calculate the final density using a mass-density-volume formula. The tutorial emphasizes organizing information in a table for clarity and provides a step-by-step guide to finding the total mass and volume. It concludes with the final density calculation and discusses the distribution of marks for the question.

What is the density of fruit syrup as mentioned in the video?

• 1.05 grams per centimeter cubed

• 1.4 grams per centimeter cubed

• 0.99 grams per centimeter cubed

• 1.2 grams per centimeter cubed

Which formula is used to calculate the density of a mixture?

• Density = Volume x Mass

• Density = Mass x Volume

• Density = Mass / Volume

• Density = Volume / Mass

How is the mass of a liquid calculated according to the video?

• Mass = Density x Volume

• Mass = Volume x Density

• Mass = Volume / Density

• Mass = Density / Volume

What is the total volume of the drink mixture?

• 320 grams

• 320 centimeters cubed

• 324.45 centimeters cubed

• 324.45 grams

What is the final density of the drink, rounded to two decimal places?

• 1.02 grams per centimeter cubed

• 1.03 grams per centimeter cubed

• 1.01 grams per centimeter cubed

• 1.00 grams per centimeter cubed

How many marks are awarded for finding the density of the drink?

• Three marks

• Four marks

• Two marks

• One mark

What is the importance of organizing information in a table as discussed in the video?

• It prevents errors in picking information from different lines

• It helps in memorizing the data

• It makes the data look neat

• It is required for the exam
