If the weight of a pot is 50.0 pounds and it covers an area of 0.03 square inches which following choices will be the pressure exerted by the pot

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

indium, and thallium have three electrons i think

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
