sir please follow me i will mark you a brainlist plz muje follow and also thank me for the question of a contact

Answer 2

Answer:

1.65g/cm^3

Explanation:

weight(w1)=20 gram, weight (w2)=90g

h=6cm,d=3cm

density of molasses=?

density (p)=m/v. m-- mass v--volume

volume of jar(cylindrical)=πr^2h=3.14x(1.5)^2x(6)=42.39cm^3

mass=w2-w1=90-20=70g

density of entire jar=p=m/v=70g/42.39cm^3=1.65g/cm^3
