Tin to Fluorine mass ratios:
1) For compound A:
38.5/12.3
= 3.13
2) For compound B:
56.5/36.2
= 1.56
The lowest whole number mass ratio is 2. It cannot be 1 because it is less than that required for compound B.
Explanation:
Accuracy is the nearness of observed values or measured values to the true value.
The difference between the measured and observed value gives the error incurred during the experimental procedure.
Here are some ways to improve the accuracy of measurements;
- Use the right instrument to make recordings and to take measurements.
- Employ the right hands and improve your technical knowledge.
- Be very careful and observant while making measurement.
- Ensure the instruments are properly calibrated.
- Make sure the experiment follows the right design.
