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 =============
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
The lower the molarity, the lower the concentration. Molarity is a measure of the concentration of a solute in a solution. A lower molarity means there is less solute dissolved in the solution, resulting in a lower concentration of the solute.
Is molarity an intensive or extensive property?
Molarity is an intensive property.
What is the relationship between weight and molarity in a solution?
The relationship between weight and molarity in a solution is that weight is directly proportional to molarity. This means that as the molarity of a solution increases, the weight of the solute in the solution also increases. Conversely, as the molarity decreases, the weight of the solute in the solution decreases.
How do you calculate moles from molarity?
To calculate moles from molarity, you use the formula: moles = molarity x volume (in liters). Simply multiply the molarity of the solution by the volume of the solution in liters to find the number of moles present in the solution.

What 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?
The lower the molarity, the lower the concentration. Molarity is a measure of the concentration of a solute in a solution. A lower molarity means there is less solute dissolved in the solution, resulting in a lower concentration of the solute.
Is molarity an intensive or extensive property?
Molarity is an intensive property.
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.
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?
First, convert the 2.14 L sample to 2140 mL. Use the ideal gas law to find the number of moles of HCl gas. Then, calculate the molarity by dividing the number of moles of HCl by the total volume of the solution (2140 mL + 668 mL).
How do you fnd the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
What is true about the molarity of a weak acid?
The molarity not depend on weak or strong.
What is the relationship between weight and molarity in a solution?
The relationship between weight and molarity in a solution is that weight is directly proportional to molarity. This means that as the molarity of a solution increases, the weight of the solute in the solution also increases. Conversely, as the molarity decreases, the weight of the solute in the solution decreases.
