.
If the density of aluminium is 2.7 g/cc then find specific gravity of aluminium.
A) 27
B) 2.7
C) 0.27
D) None​

Answer 1

Explanation:

0.27 is the answer from my side

Answer 2

Answer:

The specific gravity of aluminum is 2.7

Explanation:

Specific Gravity:

• Specific Gravity or relative gravity is the ratio of the density of a substance to the density of the reference substance.
• As it is a ratio, it is a dimensionless quantity
• Specific gravity is usually determined by the density of water at 4 degrees Celsius as the reference density.
• Given by the formula,

       $\mbox{specific gravity}=\dfrac{\mbox{density of substance}}{\mbox{density of water}}$

Given the density of aluminum is 2.7 g/cc

Density of water in CGS units is 1 g/cc

Thus, the specific gravity of aluminum is

$\mbox{specific gravity}=\dfrac{{2.7}}{1}}=2.7$

Therefore, the specific gravity of aluminum is 2.7.

So, the correct answer is option B.
