Question

1. The water in a graduated cylinder is measured at 35 ml. A ball is then put in the cylinder and the water
level rises to 52 mL. If the density of the ball is 25 g/cm3, mass of ball (in kg) is:
a. 0.425
b. 0.687
c. 2.35
d. 1.326
2 A 350 cm3 flask of glass filled with
mwater if emnty flasks weighs
AC
please tell me the answer it's urgent.​

Answer 1

Answer:

1. Given,

Volume 1 (V₁) = 35 mL

Volume 2 (V₂) = 52 mL

Volume of the ball (V) = V₂-V₁

= (52-35) mL

= 17 mL or, 17 cm³

Density of Ball (d) = 25 g/cm³

Density = Mass/Volume

= 25 = Mass/17

= 425 g = Mass

= 0.425 kg = Mass (Option A)

I couldn't understand the 2nd question.... Please write it clearly.... I hope the first solution helps.
