If you have 6.5g of a solution with a density of 0.92g/mL, what is the volume of this sample? What volume (ml) of 8.0 M solution is required to make 134.3 ml of 1.2 M solution? How much volume will 550 g of a solution with a density of 1.10 g/mL occupy? What...
ash because (1) it contains minor quantities of tridymite, sanidine, and volcanic glass, and (2) it contains notably more endellite and allophane (amorphous and relatively soluble in NaOH) than is present in the other kaolin ... H Ponder,WD Keller - 《Clays & Clay Minerals》 被引量: ...
Mercerization involves intracrystalline swelling of cellulose in concentrated aqueous sodium hydroxide (NaOH), followed by washing and recrystallization. This process is used to improve the properties of natural yarns and fabrics. The transition from cellulose I to cellulose II is not reversible, and ...
To solve the problem step by step, we will calculate the molarity and mole fraction of ethanol after diluting it with water.Step 1: Calculate the mass of ethanol Given: - Volume of ethanol = 100 mL - Density of ethanol = 0.8 g/
of cellulose, synthetic fibre, or glass fibre, and impregnating this with a 10% solution of acetyl cellulose in 90/10 methylene dichloride/ethanol, optionally adding plasticizer, e.g. dimethyl phthalate, then drying and saponifying for 50 hours at 90 C. in 30% NaOH; alternatively the fabric...

How many mL of a 53.4 wt% NaOH solution with a density of 1.52 g/mL will you need to prepare 2.000 L of a 0.169 M NaOH solution? The density of a certain aqueous solution is 1.17g/mL, and the solution is 3.57% by mass NaOH. How m...
A 15.0% by mass NaOH(aq) solution has a density of 1.1655 g/mL. What is the molar concentration of this solution? A solution of H_2SO_4 (aq) with a molar concentration of 3.97 m has a density of 1.216 g/mL. What is the ...
For a typical synthesis of support, 28 g of NaOH (Sinopharm) was dissolved in 70 mL of deionized water (10 mol/L). After that, 2 g of anatase TiO2 (Macklin, particle size = 100 nm, denoted as TiO2-Ref1) was added into the above solution with stirring for 1 h ...
The pH of the solution was adjusted by 0.5 M NaOH. The experiment was conducted at room temperature and was repeated three times. Analysis of heavy metal adsorption capacity An inductively coupled plasma-mass spectrometer (ICP-MS, agilent 7700x) was utilized to determine the concentration of ...
