Question

Calculate the average mass of these three samples: 104.2g, 3.21g, 29.0g.

Answer 1

when you add all of the numbers together, it equals 136.41. that divided by 3 = 45.47 which is the average

Answer 2

Answer : The average mass of these three sample is 45.47 g

Explanation :

Average : It is defined as the sum of all the values divided by the total number of values.

`\text{Average}=\frac{\text{Sum of all values}}{\text{Number of values}}`

As we are given the mass of three samples which are, 104.2 g, 3.21 g, 29.0 g

Now we have to determine the average mass of the given sample.

`\text{Average}=\frac{\text{Sum of all values}}{\text{Number of values}}`

`\text{Average}=(104.2g+3.21g+29.0g)/(3)=(136.41)/(3)=45.47g`

Therefore, the average mass of these three sample is 45.47 g
