Calculate the molar mass of Eugenol. IMolar Mass: The molar mass of any specific organic compound can be derived if one knows the atomic masses of organic elements such as carbon, oxygen, hydrogen, and nitrogen.. With the help of their data, molar mass can be computed. ...
How many grams of silver are contained in 4.25 moles of silver? What is the mass, in grams, of 0.034 moles of silver atoms? Question #2: Calculate the number of atoms in 200 grams of Silver (Ag).: N= Calculate the mass, in grams, of 7.35 moles of NH3. ...
RCHO+ 2[Ag(NH3)2]OH = RCOOH + 2Ag + 4NH3 + H2O For every molecule of aldehyde, 2 ions of Ag+ are used, thus n(A)/n(Ag+)=1/2 and n(B)/n(Ag+)=1/2 Now if the amount of Ag+ ions is the sum of the ions that reacted with A and the ions that reacted with B n(...
a). 5.8 g NH3 x 1 mol NH3 / 17 g NH3 = 0.34 moles NH3 PV = nRT (note: change temp of 100C to 373 K) V = nRT/P = (0.34 mol)(0.0821 Latm/Kmol)(373K) / 15 atm = 0.69 liters do the others the same way. Convert grams of material to moles by using the molar mass and...
The molar mass of an element can be directly obtained from a periodic table. It is typically given in units of g/mol. For compounds however, where two or more elements are chemically combined together, it is necessary to compute the molar mass by adding up the atomic masses of each of ...
