Moles count thenumberof atoms or molecules in a sample, while grams represent theweightof the sample. Moles are normally used in chemical formulas to represent the relative amount of each substance in the formula – in other words, how many moles of each reactant are needed to make a certai...
Grams and moles are two units that express the amount of matter in a sample. There is no "conversion formula" between the two units. Instead, you use atomic mass values and the chemical formula to do the conversion. To do this, look up atomic masses on the periodic table and use the ...
Grams to Moles Conversion: Water, like any pure chemical compound, has a definite mass-mole correspondence or conversion. The correspondence or conversion factor is the molar mass of water. A mole of water constitutes {eq}\rm 6.02\times 10^{23}\ molecules {/eq...

The calculation of mass from the molecules depends on the moles of a substance in question, which is multiplied by its corresponding molar mass to obtain the exact mass. Answer and Explanation: 1 Given data Molecules of methanol = {eq}9.48 \times 10^{24} {/eq} We use the Av...
element is listed in atomic mass units under its symbol in the periodic table. This unit is defined in such a way that the mass number of each element corresponds to the mass of one mole of the element in grams. A mole equals Avogadro's number (6.02 x 1023) of atoms or molecules. ...
All substances consist of atoms or molecules. In chemistry, it is important to measure their amounts accurately. The mole is used to express the amounts of reactants and products of chemical reactions. The mole, symbol mol, is the SI unit of the amount of substance. One mole contains exa...
One mole of a substance has a mass （equals）_to its relative formula mass in grams, contains （identical) atoms, molecules or formula units.
