Question

Ahmed places a measuring cylinder on the scales and then resets the scales to zero. He adds 100 ml water to the measuring cylinder. He then adds 25 g salt to the water. The reading on the scale is 125 g. If all the water in the cylinder evaporated, what would be the reading on the scales?

Answer 1

Answer:

250G

Explanation:

Answer 2

Answer:

Mass of stone = 113 g

Initial volume of cylinder = 30 ml

= 30 cm^3

Increased volume = 40 ml

= 40 cm^3

Volume = 40-30

= 10 cm^3

Density of stone = Mass/Volume

= 113/10

= 11.3 g/cm^3

Relative density = Density of object / Density of water at 4°C

R.D = 11.3/1

R.D = 11.3
