820 g li2so4 is dissolved into 2500 ml of solution. what is the molar concentration?

Molarity is defined as the moles of solute per liter of solution. . Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of which is 109.98 g/mol

Then we find the molarity using above equation

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

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
