What is the answer to the problem: 101 g + 25.01 g + 5.05 g?

the answer is 131.06g hope this helps

Explanation:

131.06

Explanation:

First add the decimal places “0.01 & 0.05”. Which is “0.06”.

Then add 25 & 5 which is “30”.

Then add 30 to 101, which is 131.

Then add 131 to 0.06, which is equal to “131.06”

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
