If the volume of 1.00 mole of gas is tripled, what will happen to the pressure, if the temperature remains constant

The new pressure becomes one third of the initial pressure.

Explanation:

The relation between pressure and volume at constant temperature is given by :

Let new pressure and volume be P' and V' respectively.

V'=3V (given)

So,

Hence, new pressure becomes one third of the initial pressure.

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

the answer for sodium is 0.186

the answer for rubidium is 0.251
