In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Chemists routinely perform calculations of the amount of substances necessary to carry out a chemical reaction. Textbooks refer to this topic as "stoichiometry." Chemists base all stoichiometric calculations on moles. A mole represents 6.022 x 10^23 for
Polydactyly is a hereditary anomaly that is relatively common in both humans and animals. Moles also have additional fingers. In their case, however, the irregularity compared to the five-finger formula of land vertebrates is the norm. An international team of researchers head-ed by paleontologists...
Once the maltose is broken into glucose, other enzymes act on the glucose molecules to turn them into energy for the cell to use. To make an enzyme that it needs, the chemical mechanisms inside an E. coli cell make a copy of a gene from the DNA strand and use this template to form...

In this case, the calculation of moles involves dividing the number of molecules by the Avogadro's number, multiplied by one mole.Answer and Explanation: Given data Molecules of {eq}\rm CH_3OH = 9.48 x 10^{24 } \ molecules {/eq} We use the Avogadro's number to determine mole...
Kcat is turnover number, expresed as number of substrate molecules turned into product per enzyme site per minute. Km and X are both in the same units of substrate concentration. Prism will fit Kcat and Km, each with a confidence interval. ...

How many molecules of NaCl does that contain? To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\...
2. Divide the Lowest Number Into the Others Calcium is the element with the lowest number of moles, which is 0.337. Divide this number into the others to obtain the mole ratio. In this case, it's H – 2, O – 2 and Ca – 1. In other words, for every calcium atom in the compo...
