Jimmy Ho · Answer 1

b) 7.89 g

c) 7.91 g

d) 7.97 g

Explanation:

The accepted value for the measurement is 7.92 g, while the precision of the instrument is 0.05 g. Therefore, the interval of the accepted values will be the central value plus and minus the precision, so:

- Minimum accepted value: 7.92 g - 0.05 g = 7.87 g

- Maximum accepted value: 7.92 g + 0.05 g = 7.97 g

So, the accepted interval is

7.87 g - 7.97 g

Therefore, all the values that lie within this interval are accepted. So the accepted values are:

b) 7.89 g

c) 7.91 g

d) 7.97 g
