Molar mass of aluminum ( Al ) = 26.98 g/mol

n = m / M

n = 0.50  / 26.98 

n = 0.01853 moles

hope this helps!

Answer: The number of moles of 0.50 g Aluminium is 0.0185 moles.

Explanation:

To calculate the number of moles, we use the formula:

Moles=\frac{\text{Given mass}}{\text{Molar mass}}

In the given question:

Given mass of Aluminium = 0.50 g

Molar mass of Aluminium = 27 g/mol

Putting values in above equation, we get:

\text{Moles of Aluminium}=\frac{0.50g}{27g/mol}=0.0185moles

Hence, the number of moles of 0.50 g of Aluminium is 0.0185 moles.

A diner adds sugar into their coffee until the sugar starts to precipitate. If they then add more coffee to their drink, what ty
PtichkaEL [24]

Answer:

unsaturated solution

Explanation:

This solution is made by the coffee, which is the solvent and the sugar, which is the solute. The solute dissolves in the solvent.

Sugar starts to precipitate because it cannot dissolve anymore. This means that the solution at the equilibrium point and is saturated. Since more coffee or solvent is added, the solution will now be able to dissolve more sugar. This means that the solution is unsaturated

Which of the following is improper isotope notation? Explanation: Nineteen is potassium's atomic number
sasho [114]

Answer:

C. Potassium-19 .

Explanation:

Hello!

In this case, since isotopes are known be atoms of the same element with equal atomic number but different mass number, we can consider the case of carbon which has two natural occurring ones, carbon-12 and carbon-13 whereas carbon-12 has the greatest abundance. However, isotope notation may take two forms:

1. Symbol of the element followed by a dash indicating the mass number of the isotope, for instance: C-12, K-39, and so on.

2. Name of the element followed by a dash indicating the mass number of the isotope, for instance: Carbon-12, Potassium-39, and so on.

In such a way, the improper isotope notation is C. Potassium-19 , considering that A should be K-39 because atomic symbol of potassium is K, not k.

Best regards!
