The "Ehow" website containing an excellent article on determining the ATM to molarity. It is, however, a most complex process and requires a barometer, extra long tape measure and a thermometer.

What is the molarity of the HCl solution if 240 ml of the HCl solution reacts with magnesium to produce 4.60 L of HCl gas measured at STP?
We can use PV = nRT to find moles of HCl (1 atm)(4.60 L) = n(0.08206 L*atm/mol*K)(298.15 K) moles HCl = 0.188 moles Molarity = moles of solute/Liters of solution Molarity = 0.188 moles HCl/0.240 liters = 0.783 Molar HCl =============
What does molarity of a solution indicate?
Molarity is an indication for concentration.
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
Yes, molarity is (number of moles/liters of solution). If you increase the numerator, the molarity number will be greater.
Moles of a solute per kilogram of a solvent?
The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
Is molarity represented by the symbol m?
Yes, molarity is represented by M.

If 2.14 L sample of hydrogen chloride HCL gas at 2.61 ATM and 28 C is completely dissolved in 668 ml of water to form hydrochloric acid solution Calculate the molarity of the acid solution?
PV = nRT --> n = PV/RT n = moles of HCl = (2.61 atm)(2.14 L)/(0.0821)(273+28) = 0.226 moles Molarity = 0.226 moles/0.668L = 0.338 M
What molarity of a solution indicate?
Molarity is an indication for concentration.
What does molarity of a solution indicate?
Molarity is an indication for concentration.
What is molarity pure water?
the molarity of water is 55.5.
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
Yes, molarity is (number of moles/liters of solution). If you increase the numerator, the molarity number will be greater.

The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
What is the osmotic pressure of saline?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What would happen to the molarity if you concentrate a solution?
If you concentrate a solution, the molarity (moles/liter) will increase.
How do you fnd the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Is molarity represented by the symbol m?
Yes, molarity is represented by M.
