The pressure inside of a sealed syringe of hydrogen gas is 80.0KPa with a volume of 250 Liters. What is the pressure inside of the syringe after the plunger is pulled back far enough to make final volume of the syringe 0.750 Liters? (assume the
temperature and amount of gas in the container are held constant)

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

Since we are finding the new pressure

From the question we have

We have the final answer as

Hope this helps you

i don t now

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
