In three moles of ethane(C2H6), calculate the following: (i) Number of moles of carbon atoms. (ii) Number of moles of hydrogen atoms. (iii) Number of molecules of ethane. View Solution How many molecules are present in 1 kg mole of a substance? View Solution How many molecules ar...
Although genes get a lot of attention, it’s the proteins that perform most life functions and even make up the majority of cellular structures. Proteins are large, complex molecules made up of smaller subunits called amino acids. Chemical properties that distinguish the 20 different amino acids ...
How many hydrogen molecules can be inserted into C60? Comments on the paper `AM1 treatment of endohedrally hydrogen doped fullerene, nH2@C60' by L. Tu¨ rker and S. Erkoc¸ ß[J. Mol. Struct. (Theochem) 638 (2003) 37- 40]. J Mol Struct 2005;732(1-3):239-41....
composition of each acid's molecule is described through a molecular formula. The molar mass of an acid in the literature refers to the total mass in grams for one mole (Avogadro's number) of its molecules. For example, the molar mass of hydrochloric acid (HCl, binary acid) is 36.45 g...
To calculate the number ofmoleculesand atoms in a water drop, you need to know the chemical formula of water. There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms. ...
For many years, scientists couldn’t figure out how atoms and molecules combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What’s more, living ...
Why are coordination compounds important? Why is carbon important for forming complicated molecules? Why does H_{2}O have a smaller bond angle than H_{3}O^{+}? What is the importance of hydrogen in the body? Why can water dissolve many substances?
How many moles are in 9.48×1024 molecules of methanol (CH3OH)? Determination of moles from Avogadro's number: Avogadro's number means that one mole of a unit substance is made up of 6.022×1023 particles or molecules. In this case, the calculation of moles involves dividing the number ...
The Avogadro's number is the number of particles (molecules or atoms or ions or even photons) that are contained in one mole of a substance. It is equal to 6.023×1023particles per mole. Answer and Explanation: Here we are given the volum...
If a stretch of DNA contains 808 nucleotides and 63 of them are cytosine, how many are thymine? How many double-stranded DNA molecules are in one chromosome? How many hydrogen bonds are between adenine and thymine? How many amino acids are coded for by the DNA?
