If a substance has a mass of 27.82 grams and a volume of 3.6 ml, what is the most accurate density of the substance in g/ml?

vladimir1956 [14]

7.7278 g/ml is the most accurate density of the substance.

<h3>What is density?</h3>

It is define as the quantity per unit volume, unit area, or unit length.

i.e. the mass of a substance per unit volume.

Mathematically,

$\rho =\frac{m}{v}$ ----- equation (1)

Where,

p is the density

m is the mass

v is the volume

According to the question,

Mass = 27.82 grams

Volume = 3.6 ml

By substituting the Value of m and v in equation 1.

$\rho =\frac{27.82}{3.6}$

$\rho = 7.7277777 g/ml$

Therefore,

The most accurate density of the substance in g/ml is 7.7277777 g/ml.
