The local garden centre sells lawn sand, which is a mixture of sharp sand and fertiliser (ammonium nitrate). It should be made up from a 50/50 mix of each, measured by weight. Your neighbour has bought some, but believes that the garden centre has cheated her by adding more of the sand (which is not as valuable as the fertiliser). Your neighbour has asked you to help prove that she has been cheated. Outline briefly the steps you would take to test her idea and explain briefly why you are doing each step.

well, i say that you just return it and and take another one if thats all right (easy xD)

or idk tbh im trying mah best

To test your neighbor's suspicion that she has been cheated by the garden center, you can follow these steps:

1. Measure the weight of the lawn sand: Start by measuring the total weight of the lawn sand your neighbor purchased. Use a weighing scale to accurately determine the weight. This step is important because it provides a baseline for comparison.

2. Separate the sand and fertilizer: Next, carefully separate the sharp sand and fertilizer from the mixture. This can be done manually by carefully picking out the sand particles and leaving only the fertilizer behind. The goal here is to distinguish and quantify the amount of each component.

3. Weigh the sand and fertilizer: Measure the weight of the separated sharp sand and fertilizer. Ensure that the measurements are performed accurately using a scale. This step allows you to determine the individual weights of the sand and fertilizer components.

4. Calculate the percentage of each component: Divide the weight of the sand by the total weight of the separated components (sand + fertilizer) and multiply the result by 100 to calculate the percentage of sand. Similarly, divide the weight of the fertilizer component by the total weight and multiply by 100 to calculate the percentage of fertilizer. Comparing these percentages with the expected 50/50 ratio will provide insights into the composition of the lawn sand.

5. Compare the calculated percentages with the expected ratios: Compare the calculated percentages of sand and fertilizer with the expected 50/50 ratio. If the calculated percentages deviate significantly from the expected ratio, it may suggest that your neighbor has been cheated or that there was a mistake in the manufacturing process.

By following these steps, you will be able to objectively assess the composition of the lawn sand and determine if your neighbor's suspicion is valid or if the garden center has indeed cheated her.

i would use a beaker

I found out the answer
