AQA GCSE · Question 04.1 · Quantitative chemistry
A 9 carat gold ring is made from a mixture of metals. The mass of the ring is 5.0 g. Table 3 shows the mass of different metals in the ring. Plot the data for copper from Table 3 on Figure 1.
A 9 carat gold ring is made from a mixture of metals. The mass of the ring is 5.0 g. Table 3 shows the mass of different metals in the ring. Plot the data for copper from Table 3 on Figure 1.
How to approach this question
1. Look at Table 3 to find the mass of copper, which is 0.3 g.
2. Find the "Copper" label on the x-axis of the bar chart.
3. Find the value 0.3 on the y-axis. Each small square on the y-axis represents 0.1 g. So 0.3 is three small squares up from 0.0.
4. Draw a bar for copper that reaches this height.
Full Answer
The bar for Copper should be plotted to a height of 0.3 on the y-axis.
The data for the bar chart is provided in Table 3. The question asks to plot the data for copper.
From Table 3, the mass of copper is 0.3 g.
On the bar chart (Figure 1), you need to add a new bar for "Copper". The y-axis represents the mass in g. The scale goes up in increments of 0.5, with smaller grid lines representing 0.1.
Therefore, the bar for copper should be drawn to a height corresponding to 0.3 on the y-axis.
Common mistakes
✗ Plotting the wrong value (e.g., the mass of gold or silver).
✗ Misreading the scale on the y-axis and drawing the bar to the wrong height (e.g., to 3.0 instead of 0.3).
