7.022

Explanation:

2.589x10^6/ 3.687x10^5

1. 2.589/3.687 = 0.702197 [Separate out and divide just the decimal portion first]

2.  10^6/10^5 = 10^(6-5) = 10^1  [Divide the exponent portion next]  When dividing, subtract the denominator exponent from the numerator exponent:  (6-5) = 1.  The exponent is 1.

0.702197x10^1    [Put the two pieces together: 1. and 2.]

7.02197             [Move the decimal point once to the right, which will reduce 10^1 to 10^0, or 1]

7.02197 or 7.022 to 4 sig figs

Particle exchange energy though elastic collision , hope this .

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
