If 500 ml of liquid mercury weighs 6.53 kg, what is the mass in pounds? a) 1.44 lb b) 2960 lb c ) 14.4 lb d) 7.19 lb e) 2.96 lb

The correct option is: C ) 14.4 lb      

Explanation:

The standard International unit of mass is kilogram, kg. Other commonly used units of mass are grams (g), tonne (t), pounds (lb).

The mass of 500 mL liquid mercury is 6.53 kg.

Since, 1 kg = 2.20462 lb ≈ 2.205 lb

Therefore, the mass of 500 mL liquid mercury in pounds = 6.53 × 2.20462 = 14.39619 lb ≈ 14.4 lb.  

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
