Answer:
.98 [tex]\frac{gm}{ml}[/tex]
Step-by-step explanation:
The density of any object is calculated by the formula:
Density=[tex]\frac{mass}{volume}[/tex]
In this case the Mass is 20.7 grams, and the volume is 21 ml, what you have to do now is just put the values in the formula and do the division:
D=[tex]\frac{20.7}{21}[/tex]
The division will be equal to:
D=[tex]\frac{20.7}{21}[/tex]= .98 [tex]\frac{gm}{ml}[/tex]
