Which equation describes the mass of an object in relation to its volume and density?(1 point)
Responses
m=D+V
m is equal to cap d plus cap v
m=VD
m is equal to cap v over cap d
m=D×V
m=D×V
m=DV
m=DV

What is the density of a rock with a volume of 5 mL and a mass of 13.5 grams?(1 point)
Responses
0.37 g/mL
0.37 g/mL
2.7 g/mL
2.7 g/mL
13.5 g/mL
13.5 g/mL
67.5 g/mL
density = mass/volume
density = 13.5g / 5mL
density = 2.7 g/mL
So, the correct answer is 2.7 g/mL.
What is the equation for the density of an object?(1 point)
Responses
D=Vm
cap d is equal to cap v over m
D=1m×V
D=1m×V
D=mV
cap d is equal to m over cap v
D=m×V
