Answer:

33 g

Explanation:

Given data:

Number of moles = 5 mol

Mass of compound = 165 g

Molar mass or gram formula mass = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Now we will put the values in formula.

5 mol = 165 g/ gram formula mass

Gram formula mass = 165 g / 5 mol

Gram formula mass = 33 g/mol

Aluminum hydroxide + nitric acid ➡ aluminum nitrate + water

m_a_m_a [10]

Answer:

Chemical equation:

HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O

Explanation:

Chemical equation:

HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O

Balanced chemical equation:

3HNO₃ + Al(OH)₃ → Al(NO₃)₃ + 3H₂O

Ionic equation:

3H⁺ + 3NO⁻₃(aq) + Al(OH)₃(s) → Al³⁺(aq) + 3NO₃⁻¹(aq) + 3H₂O(l)

Net ionic equation:

Al(OH)₃(s) + 3H⁺(aq) → Al³⁺(aq) + 3H₂O(l)

The NO⁻₃ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
