The question, as worded, is a little ambiguous. Rather, the question you should be asking is “What is the molarity of a 125 ml aqueous solution containing 10.0g of acetone?” Acetone is roughly 58 grams per mole. Therefore, a 125 mil solution with 10 g of acetone would contain roughly 0.17 moles, and the molarity would be roughly 1.4

Moles of solute ---------------- Liters of solution So, convert your grams to moles by dividing by the molar mass (add together the atomic masses of the solution) and then that will give you your moles. Divide that number by your 6.3 Liters. That number is your molarity.
Moles of glucose = 80g/180g/mol = 0.444 moleMolarity = 0.444/0.75L = 0.5926 M
Molarity (concentration ) = moles of solute/Liters of solution 250.0 ml = 0.250 liters 2.431 grams H2C2O4 * 2H2O ( 1mole cpd/ 126.068 grams) = 0.01928 moles H2C2O4 * 2H2O Molarity = 0.01928 moles cpd/0.250 liters = 0.07712 Molarity
the molarity is found by: 19.52g/770mL x 1 mole/156.7g x 1000mL/1L=0.618 mole i got 156.7g by using the chemical makeup of the solution SnF2: Sn's atomic number being 118.7 and rounding F's atomic number to 19.
Molarity = moles solute/liter solutionmoles solute = 7 g NaCl x 1 mol NaCl/58 g NaCl = 0.12 moles NaClliters of solution = 450.0 ml x 1 L/1000 ml = 0.450 litersmolarity = 0.12 moles/0.450 liters = 0.268 M = 0.3 M (one sig fig)
Yes, acetone is a fire hazard if present in large enough quantities.
molarity = no. of moles of solute/liter of solution no. of moles of I2 = mass in grams/molar mass = 4.65/253.81 = 0.01832 mol M = 0.01832 mol/0.235 L = 0.0780 mol/L
2.0 mol NaCl / 2.0 Litre = 2.0/2.0 = 1.0 mol/L = 1.0M NaCl
anyone who can't spell soak isn't smart enough to use acetone
If you rub acetone on super or Krazy glues it will soften them enough that they can be peeled off, or will disappear entirely if a small piece. Acetone is a solvent for these glues.
The molarity is 0.001255. Should you really be asking an AP Chem question on Wiki Answers, anyways?
[117(g NaCl) / 58.5(g NaCl/mol NaCl)] / 40.0(L solution) = [117/58.5]/40.0 = 2.00(mol NaCl) / 40.0(L) = 0.0500 mol NaCl / L solution = 0.0500 M
If you want to kill yourself, don't chill it. The reason why you must chill the acetone peroxide during the synthesis of it is because cooling it allows it to form the trimmer of acetone peroxide. Which is more stable than the dimer, which is formed if it is not cool enough. And I was joking about the first part. Don't EVER not chill the acetone peroxide when you make it. Ever. If the dimer is formed by this process, it could explode when you are filtering it, or even when you move the solution a little. It's really hard for me to stress all the dangers of making acetone peroxide.
80 gNaOH / 500 mL = (80 gNaOH / 40 gNaOH/molNaOH) / 0.500 L = 2.0 mol / 0.500 L = 4.0 mol/L
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
Molarity = moles of solute / total volume of solution (L or dm3) Moles LiBr = 97.7 g / (6.94 + 79.9) g mol-1 =1.13 mol M = n / V = 1.13 mol / 0.7500 L = 1.50 M There are only three significant figures in the mass of the solute but four in the volume, therefore, answer can not be more than three significant figures.
it has a lower content of acatone which isnt enough to get you high only partialy
H + and NO3 - are one to one, so no ratio needed here.Molarity = moles of solute/Liters of solution (500.0 mL = 0.5 Liters)M = 0.30 moles HNO3/0.5 L= 0.60 M H + ions in solution===================
