Mole is an important concept used in chemistry. It represents the amount of molecule which has the exact mass of its gram molecular mass. One mole also contains an Avogadros number of molecules.Answer and Explanation: The number of moles can be calculated using following formulas- Using ...
V∝n (where n is no of moles) V1∝n1 and V2∝n2 If some moles of O2 diffuse in 18 sec and same moles of other gas diffuse in 45sec then what is the molecular weight of the unknown gas ? . View Solution The Graham's law states that ''at constant pressure and temperature the...
Step by step video, text & image solution for In the formula P = (nRT)/(V-b)e^(-(a)/(RTV)), find the dimensions of a and b where P = pressure, n = no. of moles, T = temperature, V = volume and R = universal gas constant. by Physics experts to help you in doubts & ...
2. Calculate the moles of a product formed from each mole of reactant. What is a limiting reagent explain? The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. ... This method is most useful when there are only two...
The amount of product (mass or number of moles) produced in a chemical reaction is chemically termed as the "yield" of the reaction. The yield of a reaction is classified into three categories: (1) theoretical yield, (2) actual yield, and (3) percent yield....
for their generality is equivocal38. At one extreme, the ‘zero-force evolutionary law’ (ZFEL) states that in the absence of drivers or constraints, mean complexity tends to increase over time22,39. This could happen because increasing numbers of serial homologues or gene copies increase the ...
Example When the amount of O2 is equal to 3 moles, n(O2) = 3 mol, then the amount of ½O2 is equal to 6 moles, n(½O2) = 6 mol.Thus n(½O2) = 2n(O2).(2) The definition applies to entities B which should always be indicated by a subscript or in parentheses, e.g. ...
Explain the relation between mass, moles, and numbers of atoms or molecules, and perform calculations deriving these quantities from one another We can argue that modern chemical science began when scientists started exploring the quantitative as well as the qualitative aspects of chemistry. For exampl...
Formality is the number of moles or formula of solute ,regardless of chemical form, per litre of the solution. There is no difference between a substance’s molarity and formality if it dissolves without dissociating into ions. The formula for formality is: ...
Answer to: Determine the molecular formula for the following: A compound that contains C, H, and one O and has a molecular ion with an m/z value of...
