Answer:
<h3>0.2498mol
</h3>
Explanation:
7gN2 x 
=0.2498mol N2
Nitrogen gas has the formula so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).
618.936 joules. Multiplied by 4.182 though, not much difference, but
First of all scientific evidence is anything that is gathered using the scientific method that supports a hypothesis can be considered. According to me, a good place to start evaluating is to look at whether the evidence was collected using good scientific principles.
Good luck :)
