How many aluminum-based electrons are present in a salt where there is an #81*g# mass of aluminum ions....?

Answer 1

How many aluminum-based electrons in a salt where there is an #81*g# mass of aluminum ions....?

Well, we take the quotient, #(81*g)/(27*g*mol^-1)=3*mol#.
And thus there are #3 *mol# of aluminum ions, and since there are 10 electrons per #Al^(3+)# ions (for #Al, Z=13)#, there are #30*mol# of aluminum electrons.

Answer 2

To determine the number of aluminum-based electrons present in a salt with an 81 g mass of aluminum ions, we need to calculate the number of moles of aluminum ions first, using the molar mass of aluminum. Then, since aluminum forms ions with a 3+ charge, each ion has lost three electrons. Finally, we multiply the number of moles of aluminum ions by Avogadro's number to find the total number of aluminum-based electrons.

Answer 3

To determine the number of aluminum-based electrons present in a salt where there is an 81 g mass of aluminum ions, we first need to find the number of moles of aluminum ions using the molar mass of aluminum (Al), which is approximately 26.98 g/mol.

Number of moles of aluminum ions = mass of aluminum ions / molar mass of aluminum

Number of moles of aluminum ions = 81 g / 26.98 g/mol

Then, we use Avogadro's number, which is approximately (6.022 \times 10^{23}) mol⁻¹, to find the number of aluminum ions present.

Number of aluminum ions = Number of moles of aluminum ions × Avogadro's number

Finally, since each aluminum ion loses 3 electrons to form a 3+ charge, the number of aluminum-based electrons is three times the number of aluminum ions.

Number of aluminum-based electrons = Number of aluminum ions × 3

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
