How do you find the molar mass of aspirin?
Likewise the molecular mass of an aspirin molecule C9H8O4 is the sum of the atomic masses of nine carbon atoms eight hydrogen atoms and four oxygen atoms which amounts to 180.15 amu (Figure 2).
How many moles are in FE?
›› More information from the unit converterSee also what does the number 1000 mean The answer is 55.845. We assume you are converting between grams Fe and mole. You can view more details on each measurement unit: molecular weight of Fe or mol The SI base unit for amount of substance is the mole. 1 grams Fe is equal to 0.01790670606142 mole.
What is the molar mass of salicylic acid?
138.121 g/mol
How do you find moles from molar mass?
A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass the amount of moles of the substance can be calculated.
How do you convert millimolar to molar?
By using our Millimolar to Molar conversion tool you know that one Millimolar is equivalent to 0.001 Molar. Hence to convert Millimolar to Molar we just need to multiply the number by 0.001.
What is KHP in titration?
A commonly used primary standard for titration with sodium hydroxide solution is the weak acid potassium hydrogen phthalate or KHP (C8H5O4K). … The titration of NaOH with KHP involves adding NaOH from the burette to a known volume of KHP.
Is KHP a primary standard?
Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity is relatively inexpensive is easy to dry is neither hygroscopic oxidized by air nor affected by Carbon Dioxide (thus making it easy to weigh out) does not undergo decomposition during storage …
Is molar mass the same as atomic mass?
Answers. Molar masses of the elements are the same numeric value as the masses of a single atom in atomic mass units but in units of grams instead. Molar masses of compounds are calculated by adding the molar masses of their atoms.
Mass of KHP to Standardize a NaOH Solution
Why does KHP qualify as a primary standard?
Potassium hydrogen phthalate makes for a good primary standard because it is stable high in purity non-hydroscopic highly soluble non-toxic high in molecular weight cheap and available.
What is the theoretical molar mass of KHP?
204.23 g/moleThe molar mass of KHP is 204.23 g/mole.
What is the molar mass of KHP KHC8H4O4?
Potassium hydrogen phthalate/Molar mass
The molar mass of potassium hydrogen phthalate (KHC8H4O4 abbreviation KHP) is 204.22 grams per mole.
What is the molar mass of KHP in g mol?
204.22 g/molKHP (MWT = 204.22 g/mol) is a monobasic acid that contains one mole of neutralizable hydrogen per mole of compound. See also how much does a liger eat
What is the balanced equation for calcium hydroxide and hydrochloric acid?
How do you calculate molar mass?
The characteristic molar mass of an element is simply the atomic mass in g/mol. However molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms sum all the atomic mass of the constituent atoms.
What is a primary standard Why is KHP a primary standard Why do we need to use it in this experiment?
It forms white powder colorless crystals a colorless solution and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic and it is often used as a primary standard for acid–base titrations because it is solid and air-stable making it easy to weigh accurately.

How do you find moles from molar mass and ML?
There are two steps:
- Multiply the volume by the density to get the mass.
- Divide the mass by the molar mass to get the number of moles.
What is molarity of NaOH?
The molarity of NaOH is 2.002 x 10 –2 moles x 1000 mL/L / 25.0 mL = 0.801 Molar.
