The atmosphere contains about 5.2 x1015 t of air. What mass in metric tons of carbon dioxide is in the atmosphere if the concentration of CO2 is 395 ppm?

Explanation:

ppm is a unit of concentration that expresses the mass of a component (solute) in 1,000,000 units of mass of a mixture (solution).

Thus, 395 ppm means 395 tons of CO₂ in 1,000,000 tons of air.

To determine the amount of CO₂ in 5.2 × 10¹⁵ tons of air, multiply the amount of air by the ppm concentration of CO₂ divided by 1,000,000 (10⁶):

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.  

explanation:

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
