An empty bottle has a mass of 24,25 grams and 86,55 grams completely full-filled with water. then, water in the bottle is emptied and bottle is filled again with 123,95 grams of carbon tetrachloride solvent. which is the density of the solvent?

The density of a substance is the quotient we obtain when we divide its mass by the volume. The density is,
                          density = mass / volume
The mass of carbon tetrachloride is given to be 123.95 grams and that the volume is obtained by subtracting final weight of the completely full-filled with water bottle with the initial weight.
                              86.55 - 24.25 = 62.3 grams
Since the density of water is 1 grams/ cc. Then, the volume of the bottle is also 62.3 cc. The density is therefore,
                       density = 123.95 grams/ 62.3 cc = 1.99 g/cc

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n
