How many moles are 21.67 L of NH4CI?
Type your answer...

Answers

Answer:

0.967mole

Explanation:

Given parameters:

Volume of NH₄Cl = 21.67L

Unknown:

Number of moles = ?

Solution:

We assume that the volume was taken at standard temperature and pressure,

Then;

Number of moles = [tex]\frac{volume }{22.4L}[/tex]

Number of moles = [tex]\frac{21.67}{22.4}[/tex] = 0.967mole

Which of the following correctly shows the relationship, in terms of number of particles, of the three substances?

A. 1 mole of water < 1 mole of helium < 1 mole of aluminum

B. 1 mole of aluminum = 1 mole of helium = 1 mole of water

C. 1 mole of aluminum < 1 mole of helium < 1 mole of water

D. 1 mole of helium < 1 mole of aluminum < 1 mole of water

Answers

The answer is b but I’m not sure

The correct option which shows the relation between particles of the three substances is 1 mole of aluminum = 1 mole of helium = 1 mole of water.

What is a particle?

A particle is a small part of matter.

The term refers to particles of all sizes, ranging from subatomic particles like electrons to visible particles like dust particles floating in sunlight.

The relationship of a number of particles of the substance can be calculated by Avogadro's law

Thus, the correct option is B. 1 mole of aluminum = 1 mole of helium = 1 mole of water

3. If 12.5 grams of copper are reacted with excess chlorine gas, then 25.4 grams of
copper (II) chloride are produced. Calculate the theoretical yield and the percent
yield. Cu + Cl2 → CuCl2

Answers

Answer:

Percent yield = 99.6%

Theoretical yield = 25.5 g

Explanation:

Given data:

Mass of copper = 12.5 g

Mass of copper(II) chloride produced = 25.4 g

Theoretical yield = ?

Percent yield = ?

Solution:

Chemical equation:

Cu + Cl₂ → CuCl₂

Number of moles of copper:

Number of moles = mass/molar mass

Number of moles = 12.5 g / 63.5 g/mol

Number of moles = 0.19 mol

Now we will compare the moles of copper and copper chloride.

Cu : CuCl₂

1 : 1

0.19 : 0.19

Mass of CuCl₂: Theoretical yield

Mass = number of moles × molar mass

Mass = 0.19 mol × 134.45 g/mol

Mass = 25.5 g

Percent yield:

Percent yield = (actual yield / theoretical yield )×100

Percent yield = ( 25.4 g/ 25.5 g) ×100

Percent yield = 99.6%

A piece of mental with a mass of 106 g is placed in a 50 mL graduated cylinder.The volume rises from 20 mL to 31 mL. What is the destiny of the metal?

Answers

Answer:

9.64g/mL

Explanation:

Given parameters:

Mass of the metal = 106g

Volume of cylinder = 50mL

Volume difference = 31mL - 20mL = 11mL

Unknown:

Density of the metal = ?

Solution:

To find the density of the metal, we use;

Density = [tex]\frac{mass}{volume}[/tex]

Density = [tex]\frac{106}{11}[/tex] = 9.64g/mL
