Question

A solution is made by dissolving 8 grams of a salt in 100 cm^3 of water (density = 1g/cm^3). Assuming the volume does not change, what is the density of thesolution?A) 1.00 g/cmB) 0.92 g/cmC) 1.08 g/cmD) 1.04 g/cmE) 0.08 g/cm

Answer 1

Step 1 : Identify the given items and do necessary convertions:

Given : density = 1 g/cm^3)

• Mass = 8 grams of a salt

• Since water density is 1 g/cm3 therefore 100 cm3 water has 100 g weight.

,

• Therefore , Total weight after adding salt = 100g + 8g = 108g

• Volume = 100 cm^3

Step 2 : Calculate Density:

Density = Total mass of solution ÷ Total volume of solution.

=108g /100cm^3

=1.08g/cm^3

• T,his means that density = 1.08 g/cm3

,

• Option C is the correct answer.
