Question

Q1.A substance having a density of 0.16 g/cm³ has a mass of 1.28 g. What is its

volume?​

Answer 1

Step-by-step explanation:

Answer:

Density of a substance is defined as the amount of mass present per unit volume. In terms of formula we can write it as:

$\boxed{ \bf{ Density = \dfrac{Mass}{Volume}}} </p><p>$

According to the question,

Density of the substance = 0.16 g/cm³

Mass of the substance = 1.28 g

Substituting the information in the formula we get:

$\begin{gathered}\implies 0.16 = \dfrac{1.28}{Volume} \\\\\\\implies Volume = \dfrac{1.28}{0.16}\\\\\\\implies \boxed{ \bf{Volume = 8\:\:cm^3}}\end{gathered} </p><p>$

We know that,

1 cm³ = 1 mL

Therefore, 8 cm³ is equal to 8 mL.

Hence the volume of substance in (mL) is 8 mL.
