Question

Equal volumes of different substances having same densities:

• A. have same weights
• B. have different weights
• C. Both $A$ and $B$
• D. not enough information

Answer 1

The correct option is A have same weights

(A) have same weight

$d_1=\frac{m_1}{V_1},d_2=\frac{m_2}{V_2}$

$d_1,d_2$ are density of different substances

$V_1,V_2$ are volume of different substances

$m_1,m_2$ are weight of different substances

According to question:

$d_1=d_2=d$ and $V_1=V_2=V$

$d=\frac{m_1}{V},d=\frac{m_2}{V}$

so, $m_1=m_2$

Option A is correct.
