Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
What does normality mean in chemistry?
Normality is a way of expressing concentration, and is not used widely any more. It is the equivalent wt of a substance per liter of solution. The equivalent weight will depend on the reaction that take place, and can be the same as the molecular weight. Example: HCl has same equiv. wt. as mol. wt. because it has only 1 equivalent, i.e. one H. H2SO4 has TWO equivalents (2 H+) so, 1 molecular wt will be equal to 2 equivalent wts, and normality will be 2x the molarity.
What is the molecular mass of 1 mole of a compound whose formula is c3h7o2?
The same as the molecular weight of the compound.
What is the normality of 2.4M H2CO3?
These statements may be helpful for answering this question: Normality is equal to the number of equivalent weights of solute per Liter of solution. Molarity is equal to the number of moles of solute per Liter of solution, and to determine the number of moles, you take the weight of the solutes in solution divided by the weight of one of those solute molecule (the molecular weight). How does one relate equivalent weights to moles. The equivalent weight of a compound is equal to its molecular weight divided by its valence. The valence in this context means the same thing as the number of substitutable groups (H+s or OH-s). Carbonic acid is a diprotic acid that dissociates to release 2 ionizable H+ s. So along those lines, a 1 M solution of H2CO3 is equivalent to a 2N solution of H2CO3. If 1 molar H2CO3 = 2N H2CO3 , a 2.4 M H2CO3 with 2 ionizable groups x 2.4, or 4.8N. Sorry if you got my first answer and that confused you, the second answer (4.8) is the correct one. I confused normality with equivalent weight. The equivalent weight of an acid with a valence >1 like H2CO3 (valence = 2) is in fact less than its molecular weight, but the question was about normality, the number of equivalents present in a liter of solution which is not the same as the equivalent weight.
Is the apparent molecular weight of air at elevation same as at sea level?
The apparent molecular weight of a mixture of ideal gases depends on the concentrations of such gases in the Atmosphere. Below 100km altitude the gases in the atmosphere are very well mixed so that the concentration of all the gases does not vary (approximately) with altitude. Therefore the apparent molecular weight would not vary very much at an elevation and at sea level.
What is the equivalent weight of anhydrous sodium acetate?
The formula for sodium acetate is CH3COONa and the equivalent weight is the same as the molecular weight (molar mass) which is 82.0343 g/mol.
When is the molecular weight of an acid the same as its equivalent weight?
When the acid is "monobasic", that is, when each molecule of acid releases only one hydrogen ion as an acid.
How many mmol equal 52 meq of potassium?
Since potassium has a valence of one, its equivalent weight is the same as its molecular weight; therefore, 2.9.
Is the molecular weight the same as its atomic weight?
The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.
How do you calculate number average molecular weight given molecular weight range and fraction?
Molecular weight is just an older term for molar mass. They are the same.
Is Molecular Weight the same as Data point?
No.
Which of the following has same equivalent and molecular weight?
Nitric, nitrous, and most organic acids (acetic, propionic, butanoic, etc.) all have this property.

Will two molecules having the same molecular weight and charge have the same mobility in electrophoresis?
yes...!
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.
Equivalent weight of sodium thiosulphate is equal to its molecular weight why?
The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g; and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1 g. In case of Sodium Thiosulfate the reation proceeds as under: I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI 2 Na2S2O3 ≡ I2 ≡ Cl2 ≡ 2 e Hence Na2S2O3 ≡ 1 e Thus Molecular weight devded by 1 is the equivalent weight & hence both have same value
