Question

Density of liquid in CGS system is $0.625g/c{m}^3$ What is its magnitude in SI system?

• A. 0.625
• B. 0.0625
• C. 0.00625
• D. 625

Answer 1

Answer: (D)

We know that, density = $\frac{mass}{volume}$
In CGS units $d=0.625gc{m}^{-3}$
In SI units $d=\frac{0.625\times 10^{-3}kg}{10^{-6}{m}^3}$
$=625kg{m}^{-3}$
