Consider a perfectly insulated and sealed container. Determine the minimum volume in L of the container such that 0.37 L of wate
Nataly_w [17]

<u>Answer:</u> The minimum volume of the container must be 460.54 L.

<u>Explanation:</u>

Density is defined as the ratio of mass and volume of a substance.

\text{Density}=\frac{\text{Mass}}{\text{Volume}}&#10;           ......(1)

Given values:

Volume of water = 0.37 L = 370 mL               (Conversion factor: 1 L = 1000 mL)

Density of water = 1.00 g/mL

Putting values in equation 1, we get:

\text{Mass of water}=(1.00g/mL\times 370mL)=370g

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} ......(2)

Given mass of water = 370 g

Molar mass of water = 18 g/mol

Putting values in equation 2, we get:

\text{Moles of water}=\frac{370g}{18g/mol}=20.56mol

At STP conditions:

1 mole of a gas occupies 22.4 L of volume

Applying unitary method:

20.56 moles of water will occupy = \frac{22.4L}{1mol}\times 20.56mol=460.54L of volume.

Hence, the minimum volume of the container must be 460.54 L.

50 g of NaCl is mixed with water to make .5 L of salt water. Which is the solute?
NNADVOKAT [17]

Answer:

The correct answer to the following question will be "NaCl".

Explanation:

  • A solute is being known as the soluble material within a liquid or a solution. The solvent is available in larger quantities than those of the solute among fluid. 
  • Concentration seems to be a calculation including its quantity of solvent contained in such a liquid solution, regard to something like the solvent volume.

So that NaCl is the right answer.
