Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
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(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\Biggr)\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Big...
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
n = number of moles (which is related to the mass of the gas, i.e. 1 mol = 6.023x1023 molecules of the gas, and n = mass (in grams)/molar mass(MM)), R = the ideal gas constant, and T = the absolute temperature.What...
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...
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 are in 4.9 moles of sulfur dioxide? Avogadro's Number: The number of particles present in one mole of any substance is equal to {eq}6.022\times10^{23}{/eq} particles. This is known as Avogadro's number which can be denoted as {eq}N_A{/eq}. The units may be ...
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...
It takes two hydrogen atoms for every oxygen atom to produce this reaction, so the mole ratio between hydrogen and oxygen is 2:1. The reaction produces two water molecules, so the mole ratio between oxygen and water is 1:2, but the mole ratio between water and hydrogen is 2:2. ...
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 t
