What is the molarity of a solution that contains 16.0 g NaOH in 2.00 l of solution?

0.200 M Now substitute the known quantities and solve. Think about your result. When 16.0 g NaOH are used to make 2.00 L of solution, the molarity is 0.200 M.

What is the molarity of a solution containing 0.32 moles of NaCl in 3.4 liters?

0.094 M NaCl Calculating Molarity from Moles and Volume To get the molarity we need to divide the number of moles of NaCl by the volume of the solution. In this case that is 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.

How do you calculate sucrose in a solution?

To determine the amount of sucrose required, multiply the percentage by the amount of final solution: 0.05 x 100 g equals 5 g of sucrose. To determine the amount of water needed, subtract the weight of the sucrose from the final solution weight: 100 g – 5 g equals 95 g of water.

How do I calculate molarity?

As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.

How many moles of Ca NO3 2 are there in 75 mL of 0.25 M solution?

We're asked to find the number of moles of calcium nitrate are in 75 mL of a 0.25 molar solution of Ca(NO3)2 . rounded to two sig figs. Therefore, there are 0.019 moles of calcium nitrate in 75 mL of a 0.25M solution.

What is the molarity of a solution with a volume of 2.5 L that contains 5.0 moles of Naoh?

1 Answer. The molarity of the solution is 5.1 mol/L .

What is the molarity of a solution that contains 17g of NH3 in 0.50 l of solution quizlet?

what is the molarity of a solution that contains 17 g of NH3 in 0.50 L of solution? 17g NH3 divided by 17g/mol will give you 1 mol NH3. 17 is the molar mass for NH3. Since your 0.5L is already in liters and you now know your moles (1 mole) simply divide.

What is the difference between 0.5 moles and 0.5 M?

Thus, 0.5 mole of NaOH represents simply 20 g of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

What is a 0.5 solution?

In your case, the solution is said to have a mass by volume percent concentration of 0.5% , which means that you get 0.5 g of solute for every 100 mL of the solution.
