An aluminum alloy has a density of 2800 kg/m3.What is its specific weight?

Question

Quizplus · Accepted Answer

Specific weight is the weight per unit volume. It is given by the formula: specific weight = density x gravitational acceleration. 
Here, the density of the aluminum alloy is given as 2800 kg/m3. The gravitational acceleration is 9.81 m/s2. 
Therefore, specific weight = 2800 kg/m3 x 9.81 m/s2 = 27508 N/m3. Rounding off, we get the answer as 27500 N/m3, which is option A.
