To enter the iGlasses Competition, simply text the missing letters on the registration plate to 07710588000.In terms of mole, the gram equivalent of Mg(OH)2 is equal to 0.5 mole. Draw held iGlassesUK 1st September 4.00pm Please provide contact details if your number is withheld on texts. This means that NaOH equivalent weight is equal to mole of NaOH.įor example, Magnesium hydroxide (Molar mass: 58.32 g/mol) contains two hydroxide atoms (or can generate two OH - in solution), therefore the gram equivalent is equal to 58.32/2 = 29.16. This means that 1 gram equivalent of HCl is equal to 40 g of NaOH or 1 mole of NaOH. To calculate the NaOH gram equivalent, divide 40 by 1 which is equal to 40 g. Since bases are proton (H +) acceptors, the Gram equivalent of a base can be defined as the amount of base that combines with 1 mole of H + ion (or contains OH -).įor example, NaOH molar mass is 40 g/mol and it contains 1 hydroxide atom (or can generate one OH - in solution). In terms of mole, the gram equivalent of H 2SO 4 is equal to 0.5 mole. Gram equivalents of polybasic (polyprotic) acids:įor example, H 2SO 4 (Molar mass: 98 g/mol) contains two hydrogen atoms (or can generate two H+ in solution), therefore the gram equivalent is equal to 98/2 = 49. A method, performed by a mobile device, for assisting blind or visually impaired users navigate a room or a new and unfamiliar environment.The method includes blind user acquiring one or more images using a mobile device and invoking processing algorithms.
This means that HCl equivalent weight is equal to mole of HCl. This means that 1 gram equivalent of HCl is equal to 36.5 g of HCl or 1 mole of HCl. To calculate the HCl gram equivalent, divide 36.5 by 1 which is equal to 36.5 g. Gram equivalents of monobasic (monoprotic) acids:įor example, HCl molar mass is 36.5 g/mol and it contains 1 hydrogen atom (or can generate one H+ in solution). Since acids are proton (H +) donors, the Gram equivalent of an acid can be defined as the amount of acid that supplies (or contains) 1 moles of H + ion. Gram equivalent is a more relevant concept when working with acid and bases. The Gram equivalent (or equivalent weight) can be defined as the mass of an element that combines with or displaces 1.008 grams of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine.
