Re: How do you calculate the molar mass? « Reply #1 on: February 18, 2008, 01:11:37 PM » Mikey, I will say that 8H2O is part of the composition and you should threat like that! the rest of the calculations is yours, I can write the whole process but the rules says that ...
Now that you know what a mole is and what molar mass refers to, where do you find this number? You can find it for each element on the periodic table. If you look underneath the symbol for each element, you will find a number. The molar mass of elements is given by that number,mo...
Twenty锕昬ven EG based homopolymers were synthesized and three parameters, the molar mass (MM), the number of the ethylene glycol groups in the monomer, and the chemistry of the functional side group were varied to investigate how these affect their thermoresponsive behavior. The targeted MMs of...
Hi there im abit stuck on a similar question too, basically you have to work out Concentration of drug in the original serum in units of mM i worked that out to be 0.00512 mM, then after that it says Given that the RMM of the drug is 360g/mol, convert your answer into units of:_...
Let us assume an analytical technique which involves the identification of the chemical substances by sorting gaseous ions in the electrical and magnetic field according to their mass to charge ratios. Such a technique is said to be mass spectrometry....
Relative Molecular Mass Simply add the relative masses of the constituent elements to find the relative mass of a molecule. This is easy to do if you know the relative atomic masses of the elements in question. For example, water has the chemical formula H2O, so there are two atoms of ...
Answer to: How do you find the number of moles of a gas if the pressure is 1.00 atm, the volume is 800 L, the temperature is 325 K, and KE = 4.05...
Molar Mass: Arrhenius acids are an important class of substances in Chemistry. They are all covalent compounds whose molecular unit can dissociate at least one "H-X" bond to an appreciable degree in an aqueous solution. The composition of each acid's molecule is described through a molecular ...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% If the ratio is not 1:1, use a modified version of the formula. For example, if 35 ml of 1.25 M hydrochloric acid (HCI) is needed to titrate a 25 ml solution of sodium hydroxide (Na...
Calculating mass ratios is easy enough if you have access to a periodic table (see Resources) and the means to do basic algebra. Say you want to calculate the mass ratio of sulfuric acid, H2SO4. 1. Determine the Molar Mass of Each Element Present ...
