how many grams if sulfur must be dissolved into 1L of water to make a 2 molar solution?
How many moles do you need? Tha't M x L = moles S.
Then moles = grams/molar mass. You know molar mass and moles; solve for grams. By the way,S is essentially insoluble in water.
To determine how many grams of sulfur must be dissolved into 1 liter (L) of water to make a 2 molar (M) solution, we need to use the formula:
Molarity (M) = moles of solute / volume of solution in liters
First, let's calculate the moles of sulfur required:
Molarity (M) = 2 M
Volume of solution = 1 L
Using the formula, we rearrange it to find the moles of solute:
moles of solute = Molarity (M) * volume of solution
moles of solute = 2 M * 1 L
moles of solute = 2 moles
Now, to determine the number of grams, we need to use the substance's molar mass. Sulfur has a molar mass of approximately 32.06 grams/mole:
grams of solute = moles of solute * molar mass
grams of solute = 2 moles * 32.06 grams/mole
grams of solute = 64.12 grams
Therefore, you would need to dissolve approximately 64.12 grams of sulfur into 1 liter of water to make a 2 molar solution.
