A sample of pure zink has a mass of 4.50 g. Calculate its volume.

Answers

Answer 1

According to the given statement A sample of pure zinc has a mass of 4.50 g has a volume of 0.631 cm³.

What does "volume" mean?

A three-dimensional object's volume, expressed in cubic units (as inches, quarts, or centimetres), is its cubic capacity. the volume that a material takes up in a given space.

What is the volume formula?

As opposed to length, width, and height for a rectangular shape's area, the basic formula for volume is length, breadth, and height. The calculation is unaffected by how the different dimensions are referred to; for example, "depth" can be used in place of "height."

Calculation:

Volume= Density/Mass

Mass = 4.50 g

Density = 7.13 g/cm³

Volume = ?

Volume = 4.50 g/7.13 g/cm³

Volume = 0.631 cm³

The zinc has a 0.631 cm³ volume.

What is the mass in grams of 0.05 moles of gold?

Answers

The mass of 0.05 mole of gold is 9.85 grams.

Equation :

The following equation relates the mass and molar mass of a substance to its mole:

Mole = mass /molar mass

We can determine the mass of gold using the formula above. This is attainable as follows:

0.05 mole = gold in one mole.

Molar mass of gold = 196.97 g/mol

Mole = mass / molar mass

0.05 = mass / 196.97

Mass = 0.05 × 196.97

Mass of gold = 9.85 g

Hence, the mass of the gold is 9.85 g.

Definition of mass :

A physical body's mass is its total amount of matter.

Answers

The density of a substance (in g/dL) of a sample with a mass of 8.3 x 10-¹ dag and a volume of 4.10 mL is 202.44g/dL.

How to calculate density?

The density of a substance is the measure of the mass of matter contained by a unit volume.

The density of a substance can be calculated by dividing the mass of the substance by its volume.

According to this question, a substance with a mass of 8.3 x 10-¹ dag has a volume of 4.10 mL. The density can be calculated as follows:

1 dag = 10g0.83 dag = 8.3g

1 millilitre = 0.01 decilitre4.10millitre = 0.041 deciliter

Density = 8.3g ÷ 0.041dL

Density = 202.44g/dL

Heat is the thermal energy that is transferred from a system to its environment or from one thing to another.

This indicates that the particles have higher kinetic energy, which causes them to move and vibrate more fastly.

"The final solution's concentration would be 0.26M."

By adding extra solvent, you are lowering the concentration of the stock solution in the issue (This process is known as dilution).

Since you increased the volume of the fluid from 13 to 650 milliliters, it was diluted:

50 times = 650 mL / 13 mL

We must now take the concentration of the stock solution in order to determine the concentration of a final solution.

If the standard solution is 13M, then

The final solution's concentration would be 13M / 50 = 0.26M.
