What is the molarityk and molality of a 13% solution (by weight) of sulphric acid with a density of 1.02mL−1? To what volume should 100mL of this acid be diluted in order to preapre a 1.5N solution? Video Solution Text SolutionVerified by Experts The correct Answer is:Molality=1.5...
Molarity:Solutions possess variable amounts of solutes and solvents. The amount of solute is always less than the amount of solvent. We can express the amount of solute in moles by using the molarity. The molarity is the ratio between the moles of solute by the ...
Molarity Morality is a physical-chemical measure that mathematically determines the number of moles of a substance per volumetric unit. It is directly proportional to the number of moles of the substance and inversely proportional to the volumetric concentration o...
结果1 题目SAT2化学真题一道what is the approximate molarity of water?相关知识点: 试题来源: 解析 1 liter of water is 1000g,one mol of water weighs 18g,so each liter has 1000(g/L)/(18g/mol) = 55.5 mol/L = 55.5M 反馈 收藏
I needed to find out the molarity of HBr solution. The bottle is marked as48 % HBr. Mol. wt: 80.92 density: 1.49 I am assuming it is W/V: Here is my calculation, %/mol.wt/V=M 48/80.92 = 0.593 moles 0.593/100 =5.93M
200 mL of water is added to 500 mL of 0.2 M solution. What is the molarity of the diluted solution ? View Solution If 500 mL of a 5M solution is diluted to 1500 mL, what will be molarity of the solution obtained ? View Solution ...
atoms, for example, would weigh much more than a mole of hydrogen molecules. The molarity of a solution like gastric juice is the number of moles of substance dissolved in one liter of solution. A one-molar solution, for example, would have one mole of solute for each liter of solution....
Water is evaporated from 135 mL of a 0.188 M {eq}K_2SO_4 {/eq} solution until the volume becomes 105 mL. What is the molarity of potassium sulfate solution that results? Dilution and Concentration: When some amount...
Q6.If 33.2mL of 0.153M KOH is required to neutralize completely 26.0mL H2SO4 solution,what is the molarity of the acid?H2SO4}(aq) + 2KOH(aq) to K2SO4(aq) + 2H2O(l)Molarity=?Q7.Rank the following species according to the increasing energy needed to raise the temperature of 10.0g ...
