To standardize a solution of naoh before using it in a titration of an unknown acid, you dissolve 2.48 grams of potassium hydrogen phthalate (khp) into 100 ml of h2o. you then titrate the khp with your sodium hydroxide solution and reach the endpoint after adding 20.4 ml of naoh. what is the molarity of your sodium hydroxide solution?

The molarity of NaOH solution is 1.03 M.

Explanation:

i took the test. may i have brainliest i have 7/10 i need to rank up i have alot of points.

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
