Answer:
Explanation:
<h2>Before you use log you have to multiply the answer of 8.66 mol by 6.02⋅1023 by 3 because the answer of 8.66 mol by 6.02⋅1023 gives you the number of ammonia molecules and in each molecules there are 3 hydrogen atoms present.
</h2><h2>
</h2><h2>So it is:
</h2><h2>
</h2><h2>8.66⋅6.02⋅1023=5.21332⋅1024
</h2><h2>5.21332⋅1024⋅3=1.563996⋅1025
</h2><h2>log(1.563996⋅1025)=25.19
</h2>
