Molarity = 0.15 moles of KMnO4/0.75 L of solution Molarity = 0.20 M The molarity of this solution is 0.20 M (moles per liter). Quick Review of How to Calculate Molarity To calculatemolarity: Find the number of moles of solute dissolved in solution, Find the volume ofsolutionin liters, a...
To find molarity you will need to convert this number of grams into moles by using the molar mass of NaCl: 21gNaCl(1molNaCl58.44gNaCl)=0.36molNaCl To find the molarity, you can divide the number of moles by the volume of the solute (in liters): 0.36molNaCl0.1L=3.6MNaCl This means...
This is because atoms react with each other in known proportions in a way unrelated to atomic mass. One mole (1 mol) of anything is 6.02 × 1023 particles; 1 mol in a volume of 1 L has a molarity of 1.0. Thus 6 mol of NaCl in 8 L of aqueous solution has a molarity of 6 mol...
mass = volume x density mass = 30 ml x 0.790 g/ml mass = 23.7 g In real life, you can usually look up the density of commons liquids in reference books or online. While the calculation is simple, it's important to cite answer using the correct number ofsignificant digits. Also, pay...
hence, we get the factors of 16 are 1,2,4,8, and 16 shortcut method to find factors of a number let us see an example, to find the factors of a number using the shortcut method. consider the number as 40. 40 = 10 × 4 = (5 × 2) × 4 =(5 × 2) × (2 × 2) =...

When purified, you can use the crystals to prepare a solution of copper (II) chloride of specific concentration and volume.Answer and Explanation: Let's first calculate the number of moles {eq}n {/eq} of copper (II) chloride {eq}\rm Cl_2 {/eq} using the molarity a...
Convert moles of water to grams of water using the molar mass of water Convert grams of water to volume of water using density (1.00 g/mL) Now divide moles of solute by litres of water to get molarity, except, it’s not quite right unless, as I stated in the first sentence, the vo...
