The solute in solution B has a solubility of 10 g/100 g H₂O at 20°C. The solute in solution C has a solubility of 32 g/100 g H₂O at 20°C The solute in solution D has a solubility of 4 g/100 g H₂O at 20°C.​

Answers

Answer 1

From the arrangement of the options,  Solution A and Solution D are unsaturated.

What is solubility?

In a saturated solution, the rate at which the solute dissolves equals the rate at which it precipitates or crystallizes. This indicates that under the existing circumstances, no more solute can be dissolved in the solvent.

Solution A:

Amount of solute added: 20 g

Solubility of solute: 37 g/100 g H₂O

Since the amount of solute added is less than the solubility, Solution A is unsaturated.

Solution D:

Amount of solute added: 7 g

Solubility of solute: 4 g/100 g H₂O

The amount of solute added is less than the solubility, so Solution D is unsaturated.

The density of titanium is 4.51g/cm^3. What is the volume (in
cubic inches) of 3.5lb of Titanium? this could be helpful D=M/V

Answers

The volume of 3.5 lb of titanium is 21.47 in³.

The density of titanium is 4.51 g/cm³.The weight of titanium is 3.5 lb.

Formula used:

Density, D = M/V, where D is density, M is mass, and V is volume.

The conversion factor of 1 inch³ = 16.39 cm³.1 lb = 453.592 g.

First, we will calculate the mass of titanium.

3.5 lb = 3.5 × 453.592 g

= 1587.772 g

Next, we will calculate the volume of titanium.

Volume of titanium = Mass of titanium / Density of titanium

= 1587.772 g / 4.51 g/cm³

= 352.044 cm³

Next, we will convert the volume from cm³ to in³.

1 inch³ = 16.39 cm³.

Volume of titanium in in³ = Volume of titanium / 16.39

= 352.044 cm³ / 16.39

= 21.47 in³
