The characteristic being calculated here is the mean or the average of the data set.
To check:
(20.73 + 20.76 + 20.68 + 20.75)/4 [we divide it by 4 because there are 4 numbers]
= 82.92 / 4
= 20.73
Boyle's law
PV=const
P₁V₁=P₂V₂
V₂=P₁V₁/V₂
V₂=340.0kPa·250ml/50.0kPa=1700 ml = 1.7 l
Answer:
density = 0.822 g/mL
Explanation:
We calculate the density knowing the flowing formula:
density = mass / volume
mass = 2.98 grams
volume = 21.1 × 14.2 × 12.1 = 3625 mm³ = 3.625 cm³ = 3.625 mL
density = 2.98 / 3.625 = 0.822 g/mL
