How many sodium ions are present in 325 ml of 0.850 m na2so4?

Chemistry
1 answer:
NISA [10]3 years ago
4 0

Answer:

Na^+_{ions}=3.33x10^{23}Na^+_{ions}

Explanation:

Hello,

In this case, for the given molarity and volume of such solution, the moles of sodium sulfate are computed below:

n_{Na_2SO_4}=0.850\frac{mol}{L}*0.325L=0.276molNa_2SO_4

Now, by using the Avogadro's number, the ions result:

Na^+_{ions}=0.276molNa_2SO_4*\frac{2molNa^+}{1molNa_2SO_4} *\frac{6.022x10^{23}Na^+_{ions}}{1molNa^+} \\\\Na^+_{ions}=3.33x10^{23}Na^+_{ions}

Best regards.

How are sublimation in evaporation similar
diamong [38]

Evaporation is when a liquid turns into a gas, while sublimation is when a solid turns into a gas. Both involve absorbing energy to break apart the bonds of the substance. On the other hand, an example of sublimation is dry ice.

Vlad [161]
The answer to this question would be <span>na2so4.

Most of the metal on the first and second columns of the chemical table would have high water solubility. Silver(Ag) and iron(Fe) is a molecule that belongs to transition metal group, which did not have high solubility in the water.  Na2SO4 would be the one with highest water solubility</span>
