well i need to know why these equation equals 2Mol
the equation is:
116g por litro es 2M and 11.6g en 100mL is 2M
To understand why these equations yield a concentration of 2M, we need to use the formula for molarity.
Molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters.
Let's analyze the equation "116g per liter is 2M":
1. Start by converting the mass of the solute into moles. We need the molar mass of the solute to do this. Let's assume the solute is substance X with a molar mass of Y g/mol.
To convert grams to moles, use the formula: moles = mass (g) / molar mass (g/mol).
So, the number of moles of substance X is: moles = 116g / Y g/mol.
2. The equation states that this concentration is 2M. Therefore, we can set up the equation: 2M = moles / volume (in liters).
We know the concentration is 2M, but we don't have the volume mentioned. To determine it, we need additional information.
The second equation "11.6g in 100mL is 2M":
1. Convert grams to moles using the molar mass of substance X as before: moles = 11.6g / Y g/mol.
2. We need to convert the volume from milliliters to liters before using it in the molarity equation.
To convert milliliters to liters, divide the volume by 1000: volume (in liters) = 100mL / 1000 = 0.1L.
Now, we can confirm that the concentration is 2M for both equations by substituting the respective values into the molarity equation and ensuring they match:
For the first equation: 2M = (116g / Y g/mol) / volume (in liters).
For the second equation: 2M = (11.6g / Y g/mol) / 0.1L.
By following these steps and substituting the actual values, you can determine why both equations yield a concentration of 2M for substance X.
