What volume must 25 ml of 95% by mass of a solution H2SO4,density 1.80 g/ml, be diluted to produce 0.5 M solution? The hydrogen ion concentration is 1 ? 10^-7. What is the pH of this solution? What is the percent concentration of a 300 mM solution of CaCl2?
{eq}\rm n_{solute} {/eq} is the number of moles solute present in the solution. {eq}\rm w_{solvent} {/eq} is the mass of the solvent in kilograms. The number of moles in terms of the given mass and molar mass...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
Answer to: A solution of H2SO4(aq) with a molal concentration of 2.55 m has a density of 1.151 g/mL. What is the molar concentration of this...
Firstly, we need to determine the amount of surface and its state (i.e., the density of charges); and secondly, the reduction of mobility of ions in the presence of this surface. This charged-surface effect needs to be included (d~charged_surfaces) to enable the model to predict the ...

近年来，全国各地均出现过因被盗、损毁、雨污水顶托导致的排水井盖（箅）缺失，造成人员坠落、车辆陷落等事故，社会影响较大，为避免类似事故再次发生，依据《城镇排水与污水处理条例》第二十六条，《城镇排水管渠与泵站运行、维护级安全技术规程》CJJ68-2016对检查井盖（ ）提出了明确要求。
If we react HCl and {eq}Ca(OH)_2 {/eq}, we can say that is the neutralization reaction. Since we know HCl is an acid and {eq}Ca(OH)_2 {/eq} is a base. HCl is one of the commons acid solution for the neutralization reaction....
solute/total mass of solution If concentration is 0.3M CaCl2, that means the following: In 1000ml of solution there is 0.3mol of CaCl2 In 1000ml of solution there is 0.3 111 g of CaCl2 We can also convert 1000ml of solution into g by multiplying the volume with density of the ...
