Respuesta :

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

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.

[tex]\text{Average}=\frac{\text{Sum of all values}}{\text{Number of values}}[/tex]

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.

[tex]\text{Average}=\frac{\text{Sum of all values}}{\text{Number of values}}[/tex]

[tex]\text{Average}=\frac{104.2g+3.21g+29.0g}{3}=\frac{136.41}{3}=45.47g[/tex]

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