CALCULATIONS

For liquids:

Density = (M₁+A)  X   ρ_tw

                   (M₂₊A)

 

1^stcalculated density =( 40.966+0.058) X   0.9982 = 0.8216

                                     ( 49.783+0.058)

 

2^ndcalculated density =(40.882+0.058) X   0.9982 =0.8218

                                     (49.665+0.058)

 

Average density = (0.82161587448085+0.82187937171933)  /   2

Where,

M₁= Apparent mass of test chemical

M₂= Apparent mass of water

A = Buoyancy correction (0.001168 g/cm³, when density of air at 27°C and 760 mm Hg pressure)

 ρ_tw= Density of water at test temperature

Conclusions:

The density of test chemical was determined following OECD Guideline 109 and according to theIS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of test item was determined to be 0.82 g/cm³ at 20°C and 974.3 hPa.

Executive summary:

A study was performed to determine the density of test chemical in respective atmospheric pressure and temperature conditions.

The study was conducted in accordance with OECD guideline for the Testing of Chemicals no. 109; Density of Liquid and Solids, Adopted: 2 October 2012 and Method adapted from IS 4730:1994 (Reaffirmed 2003) Method for determination of Density of Liquids.

The mean density of test chemical was determined to be 0.82 g/cm³at 20 °C and 974.3 hPa.
