Answer:
0.7 g/mL
Step-by-step explanation:
Density can be found using the following formula.
d=m/v
where m is the mass and v is the volume.
The mass of the substance is 4.2 grams. The volume of the substance is 6 milliliters.
m= 4.2 g
v= 6 mL
d= 4.2 g/ 6 mL
Divide 4.2 g by 6 mL (4.2/6=0.7)
d= 0.7 g/mL
The density of the substance is 0.7 grams per milliliter.
