Question

when 20 drops. of water is added to a graduated cylindrical container filled with water,the water level of water rises from 10 to 20ml.calculate the mass of each drop.​

Answer 1

Explanation:

Number of drops is 20

level increased from 10ml to 20ml

level increased is 20-10=10

level increased by one drop=10/20=1/2

therefore mass of one drop=1/2ml=1/10 grams=0.1 gram{ venomous}

Answer 2

Answer:

0.5 gm

Explanation:

volume increase= 20-10= 10cm3 volume has been increased

volume by 20 drops= 10cm3

volume by 1 drop = 1/2 cm3

density of water = 1gm/cm3

mass = volume * density

mass = 1/2g = 0.5 gms
