An object weighing 90 N has a volume of 45 mL and a mass of 9.0 g. What is its density?
a. 0.10 g/mL
b. 0.20 g/mL
c. 5.0 g/mL
d. 10 g/mL
c because divided 45 to 9 to get 5.0
M*g = 90 N.
M*9.8 = 90
M = 9.18 kg
Density = 9.18kg/45mL = 0.204 kg/mL
Note: A 90-N. object has a mass of 9.18
kg or 9,180 grams.
Density= mass over volume
nope its b
Dimond mine girl is right, the answer is b
To find the density of an object, we need to use the formula:
Density = Mass / Volume
Given that the mass of the object is 9.0 g and the volume is 45 mL, we can substitute these values into the formula:
Density = 9.0 g / 45 mL
Now, let's calculate the density:
Density = 0.2 g/mL
Therefore, the correct answer is option b. 0.20 g/mL.
