Step 1
Mass of Antifreeze=(Mass of flask+anti freeze - mass of flask)
Trial 1
Mass of anti freez=(47.64-36.57)gm=11.07 gm
Trial 2
Mass of anti freez=(47.64-36.74)gm=11.08 gm
Trial 3
Mass of anti freez=(47.64-36.91)gm=11.06 gm
Let us assume volume of the solution is 10 ml then,
Density =
Trial 1
Density =
= 1.107 gm/ml
Trial 2
Density =
= 1.108 gm/ml
Trial 3
Density =
= 1.106 gm/ml
Mean density= Sum of all densities/number of trials
