There is no question on here lol
We can see from the details below that, the value of the solution's molality is 1.14 mol/Kg.
<h3>What is solubility?</h3>
The term solubility has to do with the quantity of solute that is able to dissolve in a given quantity of solvent. We have the solubility of the sodium hydrogen carbonate in water at 20 degrees as 9.6 g/100 g h2o.
Number of moles of sodium hydrogen carbonate = 9.6 g/84 g/mol = 0.114 moles
Number of moles water = 100 g /18 g/mol = 5.55 moles
Mole fraction of sodium hydrogen carbonate is obtainable by the use of the relation;
0.114 moles/0.114 moles + 5.55 moles
= 0.02
Molality of the solution = 0.114 moles/0.1 Kg = 1.14 mol/Kg

<em>Givens</em>
Solving
To find density, you need volume.
<u>Volume</u>
Volume = length * width * height
Volume = 4.5 cm * 4.2 cm * 4.0 cm
Volume = 76 cm³
<u>Density</u>
Density =
Density = 4.9 g/cm³
<u>Specific gravity</u>
The density of water is approximately 1 g/cm³.
Specific gravity =
Specific gravity = 4.9
<h3>
Answer:</h3>
Density: 4.9 g/cm³
Specific gravity: 4.9
The volume occupied by one mole of any gas at standard temperature(0o) and pressure(1 atm) is 22.4 litres. This volume is a close approximation and different gases vary slightly. The molar volume of any gas at S.T.P. is 22.4L .The mole of any gas can therefore be found using the expression on the right.
Answer:
The food coloring mixes through the hot water faster than it mixes with the cold water.
Explanation:
Pretty cool tbh lol, hope this helps!
