4. How many moles of ethanol (CH_3CH_2OH) are in 141 mg? A gallon of isopropanol (IPA) weighs 6,55 lbs. Calculate how many moles of ethanol (MM = 60.1 grams per mole) are in a gallon of this substance. How many moles of O_2 are needed to completely react with 3.8 moles of...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Answer to: A solution of CaCl2 is prepared by dissolving 1.004 g of the solid in approximately 30 mL of water. How many moles of CaCl2 does this...
The basis of doing proper stoichiometry is starting with a balanced chemical reaction. Afterward, the correct molar rations between substances in the reaction are determined through the coefficients of each substance.Answer and Explanation: Given: n=2 mol C3H8 is the amount of...
They have been found mostly in bacteria, but have also been isolated from viruses, archaea and eukaryotes. It has been estimated that 25% of all bacteria contain at least one restriction enzyme (1) and as many as 7 have been found in a single species (2) . In the early 1950s, Luria...
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?
Moles and Equivalents The equivalent unit was introduced to account for the fact that when solutes dissolve in solvent to create a solution, the number of particles dispersed depends on the valence of the solute. For example, when one molecule of KCl dissolves, it leaves two ions, or charged...
