2.50 g of an unknown base is dissolved in 289 mL of water and has a concentration of 0.216 M. What is the identification of the

AnnyKZ [126]

Answer:

The answer to your question is: A. NaOH

Explanation:

Data

mass = 2.5g of unknown base

volume = 289 ml = 0.289 l

concentration = 0.216 M

What is the base= ?

Formula

Molarity (M) = # moles / Volumen (V)

# moles = M x V

Process

# moles = 0.216 x 0.289 = 0.062 in the solution

MW NaOH = 23 + 16 + 1 = 40 g

MW LiOH = 7 + 16 + 1 = 24 g

MW KOH = 39 + 16 + 1 = 56 g

Rule of three

40 g of NaOH ------------------- 1 mol

2.5 g -------------------- x

x = 2.5 x 1 /40 = 0.062 moles is the same amount of moles in the

solution is the answer

24 g of LiOH ----------------- 1 mol

2.5 g --------------------- x

x = 2.5 x 1 / 24 = 0.104 moles

56 g of KOH ------------------ 1 mol

2.5 g -------------------- x

x = 2.5 x 1 / 56 = 0.045

Socratic an example of an atom that has no charge is one that has

aksik [14]

An example of an atom that has no charge is one that has a. 2 protons, 2 electrons, and 1 neutron.

To be neutral an atom must have the same number of protons (+) and electrons (-).

Only then will the charges cancel and give a neutral atom.

To find the molar mass of a compound, i would have to find the atomic mass of the compound and that is equal the the molar mass

Rina8888 [55]

So you find the atomic mass in amu, and the molar mass would be in grams.
