Answer:
[tex]\boxed {\boxed {\sf 4.26 \ mol \ NH_3}}[/tex]
Explanation:
This question asks us to convert liters to moles. We know that 1 mole of any gas contains 22.4 liters. This includes ammonia (NH₃), so let's set up a ratio.
[tex]\frac{ 1 \ mol \ NH_3}{ 22.4 \ L \ NH_3}[/tex]
Since we are converting 95.5 liters of ammonia to moles, we multiply by that value.
[tex]95.5 \ L \ NH_3 *\frac{ 1 \ mol \ NH_3}{ 22.4 \ L \ NH_3}[/tex]
The units of liters of ammonia (L NH₃) cancel.
[tex]95.5 *\frac{ 1 \ mol \ NH_3}{ 22.4 }[/tex]
Condense into 1 fraction.
[tex]\frac{95.5}{22.4 } \ mol \ NH_3[/tex]
Divide.
[tex]4.26339285714 \ mol \ NH_3[/tex]
The original measurement of liters (95.5) has 3 significant figures. Our answer must have the same. For the number we calculated, that is the hundredth place.
The 3 in the thousandth place (4.26339285714) tells us to leave the 6 in the hundredth place.
[tex]4.26 \ mol \ NH_3[/tex]
95.5 liters of ammonia is equal to 4.26 moles of ammonia.
