<u>Answer:</u> The molality of magnesium chloride is 4.93 m
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute
= 56.3 g
= Molar mass of solute
= 95.2 g/mol
= Mass of solvent = 0.12 kg
Putting values in above equation, we get:
Hence, the molality of magnesium chloride is 4.93 m
You can acquire the atomic mass of any chemical element by using the periodic table. I've provided an example on a document below to help you identify the components of an <em>element </em>block from the periodic table. Now if you want to find the mass of an exact amount of a substance you use moles for that. That's why it's called molar mass. To find the molar mass of a substance follow this little guide:
- Start with the number of grams of each element given.
- Convert the mass of each element to moles utilizing the molar mass from the periodic table.
- Divide each mole value by the smallest number of moles deciphered.
- Round your answer. This is the mole ratio of the element.
