Answer:

1.  [tex]CO_{2}[/tex]

Molar Mass: 44.01 [tex]\frac{g}{mol}[/tex]

Mass: 44.01 g

Number of moles: 1 mole

2. [tex]NH_{3}[/tex]

Molar Mass: 17.01 [tex]\frac{g}{mol}[/tex]

Mass: 17.01 g

Number of moles: 1 mole

3. [tex]Al(OH)_{3}[/tex]

Molar Mass: 78 [tex]\frac{g}{mol}[/tex]

Mass: 78 g

Number of moles: 1 mole

Explanation:

1. [tex]CO_{2}[/tex]

From the Periodic table:

Carbon (C) has an atomic mass of 12.01 [tex]\frac{g}{mol}[/tex]

Oxygen (O) has an atomic mass of 15.99 ≈ 16 [tex]\frac{g}{mol}[/tex]

To get the Molar Mass (MM):

MM= Atomic mass of the element * the atoms present in the formula of the element

[tex]MM = 12.01\frac{g}{mol} (1) + 16\frac{g}{mol} (2)\\MM = 44.01 \frac{g}{mol}[/tex]

Mass (g) : 44.01 g

Number of moles:  1 mole

2. [tex]NH_{3}[/tex]

From the Periodic table:

Nitrogen (N) has an atomic mass of 14.01 [tex]\frac{g}{mol}[/tex]

Hydrogen (H) has an atomic mass of 1.00 ≈ 1 [tex]\frac{g}{mol}[/tex]

To get the Molar Mass (MM):

MM= Atomic mass of the element * the atoms present in the formula of the element

[tex]MM = 14.01\frac{g}{mol} (1) + 1\frac{g}{mol} (3)\\MM = 17.01 \frac{g}{mol}[/tex]

Mass (g) : 17.01 g

Number of moles:  1 mole

3. [tex]Al(OH)_{3}[/tex]

From the Periodic table:

Aluminum (Al) has an atomic mass of 26.98 ≈ 27 [tex]\frac{g}{mol}[/tex]

Oxygen (O) has an atomic mass of 15.99 ≈ 16 [tex]\frac{g}{mol}[/tex]

Hydrogen (H) has an atomic mass of 1.00 ≈ 1 [tex]\frac{g}{mol}[/tex]

To get the Molar Mass (MM):

MM= Atomic mass of the element * the atoms present in the formula of the element

[tex]MM = 27\frac{g}{mol} (1) + 16\frac{g}{mol} (3) + 1\frac{g}{mol} (3)\\MM = 78 \frac{g}{mol}[/tex]

Mass (g) : 78 g

Number of moles:  1 mole
