Answer:
152.63 ml.
Explanation:
By proportion to get a 4.75 M solution the volume will be
(12/4.75) * 100 = 252.63 ml
So the answer is 152.63 ml.
Use Ideal gas law to solve. PV=mRT you have pressure (1.02atm), temperature (295K or 22°C), mass of KClO3(11.83g) , and universal gas constant on a molar mass basis (R=R_bar/M). Just make sure you units are consistent and use the ideal gas equation to solve for Volume. M, should be the total Molar mass for KClO3.
I believe it’s A, they form whole-number ratios in the compound
(99.63/100 x 14.003) + (0.37/100 x 15)
13.9511889 + 0.0555 = 14.0066889amu
13.95 + 0.0555 = 14.0055 (same thing just rounded numbers)
(You can round that to 14amu)
Answer is 14 amu
-1.09'C is the change in freezing point
“Freezing point depression” depends on the solvent and the molar concentration of the solute.
Sulfide is highly basic, consequently
K2S
completely and irreversibly hydrolyzes in water according to the following equation:
K2S+H2O→KOH+KSH
<h3>What is freezing?</h3>
Freezing, also known as solidification, is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.
the temperature at which a liquid solidifies specifically : the temperature at which the liquid and solid states of the substance are in equilibrium at atmospheric pressure : melting point the freezing point of water is 0° Celsius or 32° Fahrenheit.
