a sample of unknown material weighs 500 n in air and 200 n when immesersed in alcholol with a specfic gravity of 0.7 what is the mass density

The mass density is 1166.36 .

Explanation:

Given: Weight of sample in air = 500 N

Weight of sample in alcohol = 200 N

Specific gravity = 0.7 =

Formula used to calculate Buoyant force is as follows.

Hence, volume of the material is calculated as follows.

where,

= Buoyant force

= specific gravity

g = acceleration due to gravity = 9.81

Substitute the values into above formula.

Now, mass of the material is calculated as follows.

Therefore, density of the material or mass density is as follows.

Thus, we can conclude that the mass density is 1166.36 .

i'm pretty sure its b i might be wrong though!
