Question

A density bottle weight 20.25 g when empty , 40.75 g when filled with a liquid and 50.25 g when filled with water . Find (a) volume of bottle (b) density of liquid.​

Answer 1

Answer:

FIND a. VOLUME OF BOTTLE and b. density of liquid. ... therefore mass of water will be=50.25-20.25=30 g ... now given mass of bottle when it is filled with liquid is 40.75

Answer 2

$\bold\pink{†Required Answer†:}$

★Solution:-

Mass of empty density bottle = 20.25 g

Mass of empty density bottle + water = 50.25 g

Mass of empty density bottle + liquid = 40.75 g

➜Mass of the only water = (50.25 - 20.25) g = 30 g

Knowing that 1 g of water = 1 cm³

Volume of only water = 30 g

➜Volume of bottle = Volume of only water = 30 cm³

★Also, the mass of liquid only = (40.75 - 20.25) g = 20.50 g

$\bold\red{†Formula \: used†} \\ distance \: = \frac{mass}{volume}$

➜Density of liquid =

$\frac{mass}{volume} = \frac{20.50g}{ {30cm}^{2} } = 0.6833 \: g/ {cm}^{2}$
