What is the molarity of a solution that contains 0.65 moles of NaNO3 in 250 mL of solution?
Molarity (M) = moles of solute (mol) / liter of solution (L)M = mol / L
You have 250 mL of Solution, which is
250 mL x ( 1 L / 1000 mL ) = ( 250 / 1000 ) L = .25 L
Solute is just what's dissolved
Solvent is just what it's being dissolved in
Solution is the solute and the solvent.
M = mol / L
M = 0.65 mol / 0.25 Liters = 2.6 mol/L
The two numbers that you are given, 0.65 moles and 250 mL both have two significant figures, and the answer is two significant figures (2.6 mol/L)
Therefore the answer is 2.6 mol/L.

Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
What is the relationship in Cm3 and M?
Cm³ (cubic centimeters) and M (molarity) are related in the context of chemistry, where molarity is defined as the number of moles of solute per liter of solution. Since 1 liter is equivalent to 1,000 cm³, to convert from cm³ to liters, you divide the volume in cm³ by 1,000. Therefore, if you have a solution with a molarity (M), you can calculate the amount of solute in moles using the volume in cm³ by first converting it to liters.
What is molarlity?
Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in moles per liter (mol/L) and is commonly used in chemistry to quantify the concentration of a substance in a solution. Molarity is important for preparing solutions and performing calculations in chemical reactions. It helps scientists understand how much of a solute is present in a given volume of solvent.
How do you find the osmolality of a given number?
To find the osmolality of a solution, you can use the formula: osmolality (mOsm/kg) = (number of particles per solute molecule) × (molarity of the solution in moles per liter) × (1000 g/kg). First, determine the number of solute particles that dissociate in solution, then calculate the molarity of the solution. Multiply these values accordingly to get the osmolality in milliosmoles per kilogram of solvent.
What two things do you need to know in other to calculate concentration?
To calculate concentration, you need to know the amount of solute and the volume of the solution. The concentration is typically expressed as the ratio of the mass or moles of solute to the volume of the solution, often in units such as molarity (moles per liter) or mass percent.
A solution contains 85.0 g of NaNO3 and has a volume os 750 mL find the molarity of the solution?
First, convert the mass of NaNO3 to moles using the molar mass of NaNO3. Then, calculate the molarity by dividing the moles of NaNO3 by the volume of the solution in liters. Molarity (M) = moles of solute / volume of solution in liters.
