How many grams of nitrogen can we get from 2.5 moles

The answer to your question is 35.03 g

Explanation:

Data

mass of nitrogen = ?

moles of nitrogen = 2.5

Process

1.- Look for the atomic mass of nitrogen (look for in the periodic table)

Atomic mass = 14.01 g

2.- Use proportions to solve this problem. remember that the atomic mass is equal to one mol.

                         14.01 g of Nitrogen 1 mol

                            x                             2.5 moles

                            x = (2.5 x 14.01) / 1

                           x = 35.03 g of Nitrogen

the answer is c) gamma rays

hope i : )

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
