Answer:

C, 3.00 moles

Explanation:

First, balance the equation.

4Al + 3O2 ---> 2Al2O3

From the balanced equation, assuming Al is limiting, the mole ratio of Al:Al2O3 = 4:2 = 2:1,

meaning every 2 moles of Al used, produces 1 mole of Al2O3.

So, since 1.5 moles of Al2O3 is produced,

the no. of moles of Al used = 1.5 x2

= 3.0 moles

= C

A sample of a pure element has a mass of 45.6g and contains 4.19 x 10 23 atoms. Identify the element.
max2010maxim [7]
<h2>Answer:</h2>

    ZINC

<h2>Explanation:</h2>

<em>To identify the element based on the informartion given, we have to find the molar mass since this mass is unique to each element.</em>

            Molar mass = mass ÷ moles

<em>We already know the mass based on the question, as such we now need to find the # of moles.</em>

           Since 1 mole contains 6.02214 × 10²³ atoms

      then let  x moles contain 4.19 × 10²³ atoms <em>(given in the question)</em>

<em>     </em><em> </em>   ⇒   x =  (4.19 × 10²³ atoms  ×  1 mol) ÷ 6.02214 × 10²³ atoms

              x  =  0.69577 mol

<em>Now that we have the moles we can substitute it into the molar mass equation and solve for the molar mass.</em>

           ⇒ molar mass = 45.6 g ÷ 0.69577 mol

           ⇒ molar mass ≈  65.54 g/mol

                    This molar mass is closest to that of ZINC.
