Question

a measuring cylinder contains 30 cm3 of a liquid. some liquid is added until the liquid level reacjes the 50cm3 mark the reading of a balanc increases by 30g what is the density of liquid​

Answer 1

Answer:

Let d be the density of fluid.

So , Initial reading of balance, F

1

=30dg N

After the level reaches 50cm

3

Final reading of balance , F

2

=50dg N

Given that difference between final and initial reading is 30g

i.e, F

2

−F

1

=30 g

⟹50dg−30dg=30g

⟹20dg=30g

⟹d=

20g

30g

⟹d=1.5g/cm
