rewona [7]

Answer:

0.4 ml will be affect the density.

Explanation:

Given that,

A student filled the graduated cylinder up to the 9.6 mL mark.

Recorded volume = 10.0 mL

We know that,

Density :

Density is equal to the mass divided by volume.

In mathematically,

\rho=\dfrac{m}{V}

Where, m = mass

V = volume

Affect the density :

Affect the density is equal to the change in volume.

We need to calculate the affect the density

Using formula of affect the density

\rho=V'-V

Put the value into the formula

\rho=10.0-9.6

\rho=0.4\ ml

Hence, 0.4 ml will be affect the density.
