how do I convert 0.058 M to mL?
Note: M is molarity(moles/Liter) also the molecular weight for the equation is 60 g/mol
Thank you. It has been a while so I forgot how to do this.
You don't. Molarity is, as you note, mols/liter. What is the exact question? The liters can be changed to mL by multiplying by 1000; i.e., mols/1000 mL but I doubt if that is the question.
I have to use molecular weight (60 g/mol) to convert 0.058 M (58nM) to mL. my instructor wrote (M to moles to grams to mL). The answer is 3.34mL I just need to know how to get there.
sorry, just realized i left the density out. The density is 1.049 g/mL. This should help. Thanks.
To convert molarity to milliliters, you need to know the volume of the solution you have and the molecular weight of the solute. In this case, you have a molarity of 0.058 M and the molecular weight of the solute is 60 g/mol.
Here's how you can convert 0.058 M to mL:
Step 1: Calculate the number of moles of the solute.
You can do this by multiplying the molarity (0.058 M) by the volume of the solution in liters. Let's say the volume of your solution is 250 mL, which is equivalent to 0.25 L.
Number of moles = molarity × volume
Number of moles = 0.058 M × 0.25 L
Step 2: Convert moles to grams.
To convert moles to grams, you need to multiply the number of moles by the molecular weight of the solute.
Mass of solute = number of moles × molecular weight
Mass of solute = (0.058 M × 0.25 L) × 60 g/mol
Step 3: Convert grams to milliliters.
Since the density of the solution is not given, assuming a density of 1 g/mL, you can directly convert grams to milliliters.
Volume of solution = mass of solute (in grams) = (0.058 M × 0.25 L × 60 g/mol)
Therefore, the volume of the solution is 0.087 mL.
Remember, if you have the density of the solution, you would need to multiply the mass of the solute (in grams) by the ratio of mL/g, which is equivalent to mL/mL, to convert grams to milliliters.
