How many moles of ba(no3)2 are there in 0.25 l of a 2.00 m ba(no3)2 solution?

Answer : The number of moles of are 0.50 moles.

Solution : Given,

Volume solution = 0.25 L

Molarity of solution = 2.00 mole/L

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

Now put all the given values in this formula, we get number of moles.

By rearranging the term,

Number of moles of = 0.50 moles

Therefore, 0.50 moles of are there in the solution.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

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).
