Ethanol c2h5oh and methyl ether ch3och3 have the same molar mass.W hich has a higher boiling point?
ethanol has a higher boiling point- of 78°C :)
What is the molarity of the solution produced when 85.6 g of hydrochloric acid HCl is dissolved in sufficient water to prepare 0.385 L of solution?
Molar mass of HCl = 1 + 35.5 = 36.5 Number of moles of HCl = mass / molar mass = 85.6 / 36.5 = 2.345 moles Molarity = number of moles / Volume = 2.345 / 0.385 = 6.091 M
How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
Molarity = moles of solute/liters of solution ( 300 ml = 0.300 liter ) 0.250 molar KOH = moles KOH/0.300 liters = 0.075 moles KOH
How would you prepare a 1 mole solution of lactose?
Find out the molecular weight of LactoseAdd that many grams of Lactose into a 1000ml volumetric flaskMake up the volume to 1000ml with waterYour 1 Molar solution of Lactose is ready---------------The molar mass of lactose is 342,3 g/mol; the solubility of lactose is 216 g/L at20 0C. Consequently you cannot prepare a molar solution of lactose.
How do you calculate molarity for milli molar and nano molar solution?
The term molar it refers a form to know the concentration of a solution, and it is equivalent to a molar unit in a litre of solvent 1 Molar (1M) = 1 mole (molecular weight from the structure you are interested in) / 1000 mL or 1 L. Milimolar is the thousandth part from a solution 1M
What is molarity of solution containing 115g ethanol in 500 cc of solution?
5.0M Molarity is moles of solute/liters of solution. The molar mass of ethanol is 46.07 g/mol, so 115g of ethanol is 2.5 moles of ethanol. 500cc is the same as 0.5L. So 2.5 mol/0.5L = 5.0M
Can you prepare 1 liter of a .5-molar glucose solution?
The formula is C6H12O6 which is 180g/mole. Divide that in half for 90g in one liter of water for a 0.5 molar solution
How do you prepare a 2 molar salicylic acid solution?
take 276 gm of salicylic acid in 1000 ml water to prepare 2M solution of the salicylic acid.
How do you prepare the molar solution of K2Cr2O7?
Dissolve 294,185 g of potassium dichromate in 1L demineralized water.
What is the mass of 0.5623 moles of ethanol ch3ch2oh?
The molar mass of ethanol is 46g/mol. Using the formula mass = (molar mass) x (no. of moles), the mass of 0.5623mol of ethanol is approximately 25.9g.

How do you prepare 1 molar iodoacetamide solution?
What volume do you want to make. To make 1 liter, you take the 185 g (the molar mass) and dissolve in enough solvent to make the final volume 1 liter.
What is the molar mass of a solution containing 2000 grams?
Only a compound has a molar mass not a solution.
Is milli molar bigger than micro molar?
Yes, mili is 10-3 and micro is 10-6 so mili is bigger.
