Because the pot isn’t water it just gets really hot and you can burn yourself if you touch it
Answer:
0.047 M
Explanation:
Given data:
Volume of KF = 93.2 mL
Molarity of KF = 2.03 M
volume of water added= 3.92 L
Solution:
First of all we will calculate the number of moles of KF.
number of moles = Molarity × volume in litter
number of moles = 2.03 mol/L × 0.0932 L
number of moles = 0.189 mol
Molarity of solution:
Total volume = 3.92 L + 0.0932 L = 4.0132 L
Molarity = number of moles / volume in litter
Molarity = 0.189 mol/ 4.0132 L
Molarity = 0.047 M
The most accurate means of determining the purity of a substance is through the use of analytical methods. These methods, widely used in different industries, mostly involve chemical analysis, which can pinpoint the presence, identity and amount of impurities in the sample. The most simple chemical methods include gravimetry and titration. There are also the more advanced light-based or spectroscopic methods, such as UV-VIS spectroscopy, nuclear magnetic resonance and infrared spectroscopy. Chromatographic methods, such as gas chromatography and liquid chromatography, can also be used. Other methods used in testing the purity include mass spectroscopy, capillary electrophoresis, optical rotation and particle size analysis.
