Si se pesan 0.456 gramos de NaOH y se disuelven en 100.0 ml de solución. ¿cuál es la molaridad?
O 0.114 M.
O 0.134 M
0.001M
1.00 x 10-3 M

Explanation:

Hello,

In this case, we define the molarity as the ratio between the moles of the solute, NaOH here, and the volume of the solution in litres:

For that reason, one must first compute the moles of sodium hydroxide by using its molar mass of 40 g/mol:

Then, the volume in litres:

Finally we compute the molarity:

Best regards.

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

"the periodic table is arranged in order of atomic number."
