The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as khp). khp is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. in the titration, 24.46 ml of the sodium hydroxide solution was required to react with 0.1082 g khp. calculate the molarity of the sodium hydroxide.

Explanation:

Moles of KHP :

Given, Mass of KHP = 0.1082 g

Molar mass of KHP = 204.22 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the reaction shown below:

KHP + NaOH ⇒ KNaP + H₂O

1 mole of KHP reacts with 1 mole of NaOH

So,

of KHP reacts with of NaOH

Moles of NaOH =

Volume = 24.46 mL = 0.02446 L ( 1 mL = 0.001 L)

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

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
