Answer:
0.21mol Ar (g)
Explanation:
To convert from litres to moles at STP we must divide the amount of litres by 22.4.
4.7 / 22.4 = 0.21mol Ar (g)
NH₄Cl → NH₄⁺ + Cl⁻
NH₄⁺ (the ammonium cation)
The volume of NaOH solution is 0.532 L.
<em>Step 1</em>. Calculate the <em>moles of NaOH</em>.
Moles = 11.5 g NaOH × (1 mol NaOH/40.00 g NaOH) = 0.2875 mol NaOH
<em>Step 2</em>. Calculate the <em>volume of NaOH</em>
Volume = 0.2875 mol NaOH × (1 L NaOH/0.540 mol NaOH) = 0.532 L
