If 6.4 miles of Fe react with excess O2, how many miles of Fe2O3 can be formed? 4 Fe + 3 O2 -> 2 Fe2O3

Yuri [45]

I'm assuming that by "miles" you mean moles.

If O2 is the excess reactant, that means Fe is the limiting reactant. That means that the amount of product being formed depends on the amount of Fe reactant present. To calculate the moles of Fe2O3 formed, start with the given 6.4 moles of Fe and use the mole to mole ratio given by the reaction as shown below:

6.4 mol Fe x $\frac{2 mol Fe2O3}{4 mol Fe}$ = 3.2 mol Fe2O3

How many moles are in 5.4x1024 molecules of C4H2F7I, heptafluoro-1-iodobutane? Group of answer choices

jasenka [17]

Given :

Number of molecules of $C_4H_2F_7I$ .

To Find :

How many moles are in given number of molecules.

Solution :

We know, in 1 moles of any element/compound contains $6.022\times 10^{23}$ at atoms/molecules.

So, number of moles in $5.4\times 10^{24}$ molecules are :

$n = \dfrac{5.4\times 10^{24}}{6.022\times 10^{23}}\\\\n = 8.97 \ moles$

Therefore, number of moles are 8.97 .
