Answer:
Density = 0.0007667 Kg/cm³
Explanation:
Given the following data;
Mass of empty beaker = 0.50 kg
Volume of solution = 300 cm³
Mass of glass+solution = 730 g
To find the density of the solution in the glass;
First of all, we would convert the value in grams to kilograms.
Conversion:
1000 grams = 1 kg
730 = X kg
Cross-multiplying, we have;
X = 730/1000 = 0.73 kg
Next, we would determine the mass of the solution.
Mass of solution = Mass of glass+solution - Mass of empty beaker
Mass of solution = 0.73 - 0.50
Mass of solution = 0.23 kg
Lastly, we would solve for the density of the solution;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the formula;
Substituting into the formula, we have;
Density = 0.0007667 Kg/cm³
