Question

The following observations were taken, while determining R.D. of a liquid: Weight of the solid in air = 0.1 kgf Weight of the solid in liquid = 0.08 kgf Weight of the solid in water = 0.06 kgf Calculate:
(i) The apparent loss of weight of solid in water.
(ii) The apparent loss of weight of solid in liquid.
(iii) R.D. of the liquid​

HI DEAR SHRESTA HERE !!!!PLS FOLLOW ME FRNDS

AND THANK MY ANSWER TOO,,,,

(a) Apparent loss of wt. of solid in liq. = (0.100 - 0.080) kgf = 0.020 kgf.

(b) Apparent los of wt. solid in water = (0.100 - 0.075)kgf = 0.025 kgf.

(c) R.D of liq. =  = 0.8

(d) Density of the liquid = R.D. x 1000 kg m-3

                                    = 0.8 x1000

                                    = 800 kg m-3
