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.

Two gases helium and x are released from one end of an evacuated long cylinder at the same time if it takes helium atoms 3 times
Gemiola [76]

Answer:

Hypoflorous acid, HOF

Explanation:

From the question, we're told that the helium atoms effuses 3 times than the said gas X.

We can determine the rate of effusion by using the formula

r is inversely proportional to 1/√M, where M is the molecular mass of the gas.

And also,

r is inversely proportional to 1/t, where t is the time taken for effusion.

From both formulas I listed, we can conclude that t is directly proportional to √M. And thus we proceed.

The molecular mass of Helium is 4.

tHe = tX/3, where tx is the time taken for the unknown gas X

As of yet, we don't know the molecular mass of X. Next, we say that

tX/tHe =√Mx/MHe

3 = √Mx/4

If we square both the sides, to remove the square root, we have

9 = Mx/4

Mx = 36

The molecular mass of the unknown gas X is 36.
