How many atoms are in one mole of carbon? Mole: A mole is a unit to count atoms or molecules. When we have a mole, we are counting one Avogadro's worth(NA=6.022×1023)of these atoms or molecules. The mole is an important quantity because it is also considered as a state function,...
How many atoms and bonds are found in one molecule of adenine? Adenine: Adenine, represented by A, is a nucleotide that is present in the DNA. It is complementary to the base Thymine (T). In RNA, it is present against the base Uracil. It has two carbon-nitrogen rings and so...

How many moles are in 16.48 g Mg? Answer in units of mole. Molar Mass: One mole is defined as {eq}\displaystyle 6.022\ \times\ 10^{23} {/eq} atoms or molecules. Now since one atom or molecule has a unique mass due to the atomic model, each measurement of one mole will have a...
How many moles are in 43.5 grams of {eq}Cl_2 {/eq}? Molar Mass: The mole is the SI unit used to express the amount of substance. We bridge the mass of a substance and its amount in moles with the molar mass. The molar mass is the mass of one mole of a substance. ...
Have you ever wondered how many atoms are in a drop of water or how many molecules are in a single droplet? The answer depends on your definition of thevolumeof a droplet of water. Water drops vary dramatically in size, so this starting number defines the calculation. The rest of it is...
To do this, look up atomic masses on the periodic table and use the formula mass to know how many atoms of each element are in a compound. Remember, subscripts in a formula indicate number of atoms. If there is no subscript, it means there is only one atom of that element in the fo...
