* An empty density bottle weighs 22 g. When filled
completely with water, it weighs 50 g. When filled
completely with brine solution, it weighs 54 g.
Calculate (a) volume of density bottle (b) density
of brine solution. [(a) 28 cm3 (b) 1.14 gcm-]

Answer:
● Mass of empty bottle = 22g
● Mass of bottle with water = 50g
● Mass of bottle with brine sol = 54g
♤ Mass of water = 50-20=30g
☆ Density of water =1
♤ So the volume is water = 30 cm3
♤ So the volume of bottle = 30 cm3
♤ So the volume of brine sol. = 30 cm3
☆ Density = mass ÷ volume
♤ So the density of brine solution is
♤ M÷V= 54 ÷ 30 = 1.8 g/cm3
Hope the answer is helpful

Answer:
a) 28 cm³
b) 1.14 g/cm³
Step-by-step explanation:
Volume of density bottle:
50 g- 22 g=28 g = 28 cm³
Density of brine solution:
(54 g-22 g)/28 cm³= 1.14 g/cm³
