How many moles are in C9H8O4?
Ok, C9H8O4 has a molar mass of 180 g/mol divide the 2; 180/41.4 and you end up with mols = 4.347 multiply by avogradros number (6.022e23) and you end up with molecules. 0.150 mole C9H8O4 x = 3.61 x 10 23 O atoms 1 Answer use the molar mass of aspirin to determine how many moles you have in that sample.
How many moles of C9H8O4 are in a 0.500 g tablet of aspirin?
FREE Expert Solution
Thus, the number of moles of C9H8O4 in a 0.500-g tablet of aspirin is 2.8×10–3 mol.
How do you calculate moles in aspirin?
Calculate the moles of substance by dividing the mass of substance in grams by the molecular weight in amu. In this case, the aspirin tablet contains 250 mg, or 0.250 g. Therefore, 0.250 g ÷ 180.17 amu = 0.00139 moles of aspirin.
How many moles of aspirin C9H8O4 contain 0.480 mole of O?
Step-1Given:Moles of O = 0.480 mol O1 mol of C9H8O4 = 4 mol of OThus we can use the conversion factor, 0.480 mol of O = 0.480 mol of O = 0.12 mol of C9H8O4Thus 0.12 mol of aspirin, C9H8O4, contain 0.480 mole of O.
What is the formula for moles to grams?
In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
What is the mole of HCl?
Using periodic table you can find molar mass of HCl, which is 36.458 g/mol.
How many molecules are in a mole of aspirin?
This means that one mole of aspirin will have a mass of 180.157 g . Now that you know how many moles of aspirin you have in your sample, use the fact that one mole of a substance contains 6.022⋅1023 molecules of that substance – this is known as Avogadro’s number.
Why is the purity of aspirin important?
It is important to ensure that the purified product is actually Aspirin. This is because if it is not Aspirin, then testing the purity of it will become useless. … When water is added to aspirin, it splits the ester bond that is formed when salicylic acid reacts with ethanoic anhydride.
How much atoms are in a mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).
How many molecules are in a mole?
The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.
How many atoms are there in 1.50 moles carbon?
Explanation: In the given formula, there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.
