Answer: 17.62 g/mol
Explanation:
Data:
m = 300.1 g
compound: NH3 (the number 3 is a subscript)
n = ?
Formula:
n = mass in grams / molar mass
Solution:
1) Calculate the molar mass
N: 14.007 g/mol
H: 3*1.008 g/mol
-------------------
14.007g/mol + 3*1.008g/mol = 17.031 g/mol
2) Calculate the number of moles
n = mass in grams / molar mass = 300.1 g / 17.031 g/mol = 17.62 mol
Answer: 17.62 mol
Metal has its properties to use for structers that need to be sturdy thats its main function non metal such as wood can be used for many things but mostly for buildin houses thats its main function metalliod such as geranium is best used as a semi indicator
The given compound 3-chloro-2,2,5-trimethylhexane is an optically active compound .
Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .
It has chiral center.
Here the chiral carbon has 4 distinct groups such as : chlorine , hydrogen , 2-methylpropyl , tertbutyl .
<h3>What is di-symmetry?</h3>
Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .
<h3>Chiral center :</h3>
Have Sp3 hybridized center (4sigma bond ) .
4 distinct group is attached to the chiral atom. form non -superimposable mirror image .
<h3>What is optical isomerism ?</h3>
Same molecular formula and same structural formula . also have same physical and chemical properties .
They differ in their behavior towards plane polarized light (ppl) .

q = mC∆T
q = (30.0g)(0.900J/goC)(50oC)
q = 1350 J
So, the right answer is 1350 J
