Answer:0.5 g/cm
Explanation:
calculate the density : we'll use the formula below
density = volume over mass
Usually, density will have units of
g
m
L
when dealing with a liquid or units of

when dealing with a solid.
The mass has units of grams,
g
.
The volume can have units of
m
L
or
c

The average of the following set of measurements is 20°C.
To find the average of the given set of measurements
Given:
Set of measurements = 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C
Number of Observations = 7
Average = Sum of observations/Total number of observations
Sum of observations = 27°C+12°C+31°C+19°C+23°C+11°C+17°C
= 140
Total number of observations = 7
Substitute the values in the formula
= 140/7 = 20°C
Therefore, the average of the following set of measurements is 20°C
