How to convert molecular weight from g/mol to lb/mol? Calculate the moles of Zn(NO3)2 in 143.50 g of this substance. Convert a mass of 6.16/lb to grams (2.2 pounds =1 kilogram). Show calculations. What is composition stoichiometry in chemistry?
(Note: the molecular weight of NaCl is 58.44 g/mol.) This time, the solute has a valence of 2, as NaCl separates into Na+ and Cl-. The equation to get mEq is therefore [(30 mg)(2)]/(58.44 mg/mmol) = 1.027 mEq. Since there are 400 mL = 0.4 L, the concentration in mEq/L...
To calculate the equivalent weight of an acid and a base, we need to understand the concepts of molecular weight and valency factor. The equivalent weight can be calculated using the formula:
How do you convert 46,756,790mg, into kg? How to calculate the weight of a certain amount of water at room temperature? What is the mass of a proton and neutron? What is the mass of an electron? Calculate the density of a solid cube that measures 5.18 cm on each side and has a...
How do you calculate the pH of a buffer solution when base is added? To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is sub...
Calculate the compound’s molecular weight using the atomic weights provided in the periodic table of the elements. Multiply the number of each type of atom by its molecular weight and then sum the products. In the case of aspirin, the molecular weights of carbon, hydrogen and oxygen are 12.0...
How would you calculate the entropy change in a chemical reaction ? How is it helpful in discussing the spontaneity of the reaction ?
Add these values together foreach different atomin the molecule. This will give you themolecular massof the molecule. This is equal to the number of grams in one mole of the substance. Divide the number of grams of thesubstanceby the molecular mass. ...
(NIH, USA) was used to process the acquired TEM images to calculate mean size and size distribution of the single particles in the NMs preparations. For the anisotropic NMs (e.g. Ag nanowires, TiO2nanorods, etc.), both longitudinal and transversal (length and width) dimensions were assessed...
What is a mole? How do you calculate mole fractions?Mole Concept:The amount of a substance can be expressed using different units depending on the nature of the compound. For solids, the amount is usually expressed as mass while for the liquids, their amounts are usually expressed as volume...
