The specific gravity of a sample of concentrated nitric acid is 1.42. What is the volume in liters at 20oC
occupied by 145.3 g of this concentrate nitric acid?
change specific gravity to density.
Volume=mass/density
thank you
To find the volume of a substance, we can use the equation:
Volume = Mass / Density
In this case, the mass of the concentrated nitric acid is given as 145.3 g and the specific gravity is given as 1.42. Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance, usually water.
Since we are given the specific gravity and not the density directly, we need to convert it to density. The density of water at 20 degrees Celsius is approximately 1 g/cm^3 or 1000 kg/m^3.
To calculate the density of the nitric acid, we multiply the specific gravity by the density of water:
Density of nitric acid = Specific Gravity × Density of Water
Density of nitric acid = 1.42 × 1000 kg/m^3 = 1420 kg/m^3
Now, we can calculate the volume using the formula mentioned earlier:
Volume = Mass / Density
However, before we proceed, we need to convert the mass of nitric acid to kilograms:
Mass = 145.3 g = 145.3 g / 1000 = 0.1453 kg
Now, we can substitute the values into the formula:
Volume = 0.1453 kg / 1420 kg/m^3 = 0.000102 m^3
Since the question asks for the volume in liters, we can convert the result to liters by multiplying it by 1000:
Volume = 0.000102 m^3 × 1000 = 0.102 liters
Therefore, the volume occupied by 145.3 g of concentrated nitric acid at 20°C is approximately 0.102 liters.
