Solubility of KMnO4 in water is 6.4 g/100mL Which means maximum of 6.4 g of KMnO4 can dissolve in 100 mL of water. ... And in given situation, 0.35 moles are added to 500 mL of water which is off the limit and thus it cannot be dissolved completely.
Answer:
m = 23.42 g
Explanation:
The question is incomplete, but I found this with these data:
<em>"A chemistry student needs 10.00 g of isopropenylbenzene for an experiment. He has available 120. g of a 42.7% w/w solution of isopropenylbenzene in carbon tetrachloride. Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution'' button. Round your answer to 3 significant digits"</em>
If your data is different, you only need to replace the data here in the procedure and you should be fine.
Now, this actually is pretty easy to solve. You need 10 g, and you have 120 g of 42.7% solution of isopropenylbenzene in carbon tetrachloride.
Basically, the percent means the following:
For every 100 g of solution of tetrachloride, we have 42.7 g of isopropenylbenzene. And we just need 10 g, so, to know if we have enough solution we only have to do the following calculation:
%w/w = msto / msol * 100
From here, we just solve for mass of solution. If the solution is more than 120 g, then we click no solution, so let's see how much is the result:
42.7 = 10/msol * 100
msol = 10/42.7 * 100
<h2>
msol = 23.42 g</h2><h2>
We have enough solution.</h2>
The type of rock and the climate determines the rate at which weathering occurs
Answer:
The inner diameter of the tube is 0.4410 cm.
Explanation:
Height upto which mercury is filled = 12.7 cm
Mass of mercury = 105.5 g
Density of mercury = 13.6 g/mL =
Volume of mercury:
A mercury in cylindrical glass tube is at height of 12.7 cm.
The radius of the inner diameter of the glass tube = r
Volume of cylinder = 
r = 0.4410 cm.
