    The density of acetic acid at 30°C = 1.0354_g/mL

    Explanation:

    specific gravity of acetic acid = (Density of acetic acid at 30°C) : (Density of water at 30°C)

    Therefore, the density of acetic acid at 30°C = (Density of water at 30°C) * (Specific gravity of acetic acid at 30°C)

    = 0.9956 g/mL * 1.040

    = 1.0354_g/mL

    Specific gravity, which is also known as relative density, is the ratio of the density of a substance to the density of a specified standard substance.

    Generally the standard substance of to which other solid and liquid substances are compared is water which has a density of 1.0 kg per litre or 62.4 pounds/cubic foot at 4 °C (39.2 °F) while gases are normally compared with dry air, with a density of 1.29 grams/litre or 1.29 ounces/cubic foot under standard conditions of a temperature of 0 °C and one standard atmospheric pressure
