kari74 [83]

In vaporization, particles become really excited and sort of jiggle around.

Calculate the molarity of a solution consisting of 65.5 g of K2S0 4 in 5.00 L of solution.

tia_tia [17]

Answer:

Molarity is 0.075 M. 

Explanation:

Moles:

${ \tt{ = \frac{65.5}{RFM} }}$

RFM of potassium sulphate :

${ \tt{ = (39 \times 2) + 32 + (16 \times 4)}} \\ = 174 \: g$

substitute:

${ \tt{moles = \frac{65.5}{174} = 0.376 \: moles}}$

In volume of 5.00 l:

${ \tt{5.00 \: l = 0.376 \: moles}} \\ { \tt{1 \: l = ( \frac{0.376}{5.00} ) \: moles}} \\ { \tt{molarity = 0.075 \: mol \: l {}^{ - 1} }}$
