How many grams of magnesium are needed to completely react

Verizon [17]

97.22 grams of magnesium is needed.

<u>Explanation:</u>

The molar ratio of Mg to O2 to make MgO is 2:1

Here, we have 2 moles of O2, therefore we need 4 moles of Mg.

1 mol of Mg = 24.305 g

Therefore

4 moles of Mg = 4 $\times$ 24.305 g

= 97.22 g

Hence we need 97.22grams of magnesium are needed to completely reactwith 2.00 mol of O2 in the synthesis reaction that producesmagnesium oxide.

How many moles of Ba(NO3)2 are there in 0. 25 L of a 2. 00 M Ba(NO3)2 solution? Use Molarity equals StartFraction moles of solut

ANEK [815]

The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.

Molarity has been defined as the moles of substance in a liter of solution. Molarity has been expressed as:

$\rm Molarity=\dfrac{Moles}{Volume}$

<h3>Computation for moles of Barium nitrate</h3>

The given barium nitrate solution has the volume of 0.25 L.

The molarity of the solution has been 2 M.

Substituting the values for the moles of Barium nitrate

$\rm 2=\dfrac{Moles}{0.25}\\
 Moles=2\;\times\;0.25\;mol\\
Moles=0.5\;mol$

The moles of barium nitrate in the solution has been 0.5 mol. Thus, the correct option is B.
