Question

A solid has a volume of 8 cm^3. When weighed on a spring scale calibrated in grams, the scale indicates 20 g.
What does the scale indicate if the object is weighed while immersed in a liquid of density
2 g/cm?
(1) 16 g
(2) 10 g
(3) 12 g
(4) 4 g​

Answer 1

Answer:

Your answer is (d) 4 g

_________________

Volume= 8 cc

Density= Mass/Volume

Mass = 8 cc × 2 g/cm³

Mass = 16 g

Therefore,8 cc of this liquid has a mass of 16 g

scale indicates if the object is weighed while immersed in a liquid of density 2g/cm³

= ( 20-16 )=4 g
