Question

. The mass of density bottle is 19 g when dry and empty, 45 g when filled with water and 40 g
when full of liquid x. Calculate the density of the liquid x
Please answer the question step by step

Answer 1

Answer:

0.81 g/cm3

Explanation:

Mass of empty bottle = 19g

Mass of water and the bottle and water = 45g

Therefore, Mass of water only = 45g - 15g = 26g

Mass of liquid x + bottle = 40g

Therefore, Mass of liquid x = 40g - 19g = 21g

So now this explanation must be getting a bit messy but try to understand ok?

Now since we cannot find liquid x's density, at least we have density of water.

So we can now find the Relative Density of liquid x!

Easy!

Relative Density ( R.D.) of liquid x = mass of liquid / mass of water

                                                        = 21g / 26g

                                                        = 0.81g/cm3

Thanks
