The density of water at 30*C is 0.9956g/mL. If the specific gravity of acetic acid is 1.040 at 30*C, what is the density of acetic acid at 30*C?

sp g. = density HAc/density H2O

1.040 = (density HAc)/(0.9956 g/ml)
solve for density HAc

To find the density of acetic acid at 30°C, we can use the concept of specific gravity. Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water.

Given that the specific gravity of acetic acid is 1.040 at 30°C, we need to determine the density of acetic acid relative to the density of water at the same temperature.

The density of water at 30°C is given as 0.9956 g/mL. This means that 1 mL of water at 30°C has a mass of 0.9956 grams.

To find the density of acetic acid, we can use the formula:

Density of acetic acid = Specific gravity of acetic acid × Density of water at 30°C

Substituting the values into the formula:

Density of acetic acid = 1.040 × 0.9956 g/mL

Simplifying the calculation:

Density of acetic acid = 1.034 g/mL

Therefore, the density of acetic acid at 30°C is approximately 1.034 g/mL.
