What is the molar mass of strontium phosphate?
Well, honey, the molar mass of strontium phosphate is approximately 182.24 grams per mole. It's like the weight of all the strontium and phosphate atoms in one mole of the compound, simple as that. So, if you need to calculate some stoichiometry or impress your chemistry teacher, now you know!
What formula is a polyatomic ion?
Some major polyatomic ions include PO4 charge -3 PO3 charge -3 CO3 charge -2 ClO4 charge -1 NH3 charge +1 NO3 charge -1 NO2 charge -1 If you need anymore than look up polyatomic ions in Google.
What is the molar mass of c-phycocyanin?
The alpha chain is 18 kda and the beta is 21 kda. But usually Phycocyanin exists as trimer along with some linker peptides. The molecular weight of trimer is 121 kda
What steps are used to convert an empirical formula into a molecular formula?
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
What are some advantages of molecular formulae?
With a molecular formula we can calculate the molar mass and the chemical composition of a compound, also we can write chemical equations.
Distinguish between ideal and real stoichiometric calculations?
The theoretical yield of a reaction is the amount of some product, usually given in mass units of grams, that you would expect to get if the reaction based on a stoichiometric calculation not actually "running" the reaction in the laboratory. The actual yield is just that,it is the actual amount of product, in grams you actually produced after really running the experiment in the lab.Actual yield data comes from experimentally determined results. You can not "calculate" it.
What are the major sources of error in your determination of the molar mass -?
Without more details this is a shot in the dark but I assume that you have the moles and weight of the compound. You then calculated the molar mass from these numbers. The sources of error with doing this experimentially is that you may have lost some of the sample in transferring, you may have weighed the sample incorrectly, and you could have made mistakes in calculations (all human errors).
Can you cite some examples in solving problems regarding with molar concentration?
Example: 0,5 molar concentration of sodium chlorideThe molar mass of NaCl is 58,44 g; so 0,5 molar is 29,22 g/L
Having a misclibrated thermometer of 3 higher than actual what will be its molar mass?
sorry, but that makes no sense unless put into some context that I don't know. First, 3 of what unit higher, second thermometer is temperature, which does not relate to molar mass. Molar mass stays constant on an element or compound.

What is the molar mass of C?
The alpha chain is 18 kda and the beta is 21 kda. But usually Phycocyanin exists as trimer along with some linker peptides. The molecular weight of trimer is 121 kda
Some dilute sulfuric acid H2SO4 has a concentration of 4.90g per dm3 what is the concentration in mol per dm3?
98 g per dm3 would be 1 molar - so 49 g would be 0.5 molar , so 4.9 g is 0.05 mol per dm3 or 0.05 mol.dm-3
What is the molar mass of DNA?
This sounds like a homework question, so instead of answering it directly, I'll give some hints. * The DNA molecule comes in many sizes. Humans have 46 diploid chromosomes. The mass of DNA in a single human cell is on the order of 6.64e-12 grams. Apply this information to determine an average mass of a human chromosome. * The mass of a mole of any molecule is the mass of a single molecule multiplied by Avogadro's Number. * To make this more interesting, take your finding of the molar mass of DNA and determine the weight of one mole in a unit you are intimately familiar with, such as pounds. (It's a stupendously large number).
