First, find its empirical formula:
C9H8O4
Then find the atomic masses of C, H and O:
12.01, 1.01, 16.00
Then multiply those numbers by the number of each of them in Aspirin:
12.01 X 9 = 108.09, 1.01 X 8 = 8.08, 16.00 X 4 = 64.00
Then add those three numbers up to get Aspirin's molar mass:
180.17
Then divide each of those three numbers by Aspirin's molar mass and multiply by 100%:
C = 60.00%, H = 4.48%, O = 35.52

What is the literature value for the melting point of aspirin?
melting point- 136 degree C boiling point- 140 degree C
Atom economy of aspirin?
C7H6O3............+........... C4H6O3 ----> C9H8O4 + CH3COOHsalicylic acid ....................aspirin(Mr=138)......................... (Mr=180)So besically, to work out the percentage atom economy of aspirin you have to divide the useful product (so in that case we are dividing salicylic acid to get the percentage mass of aspirin(of the useful product) by the mass of the reactants (aspirin)and then multiply by 100%to give you the percentage atom economy :)So it is: (138/180) x 100 = 76.6:)))
How many joules are absorbed by the water with a mass of 5kg in orderto risethe temperature from 30 c to 65 c?
To calculate the energy absorbed by the water, you can use the equation Q = mcΔT, where Q is the energy absorbed, m is the mass of water (5kg), c is the specific heat capacity of water (4186 J/kg°C), and ΔT is the change in temperature (65°C - 30°C). Plugging in the values gives Q = 5kg * 4186 J/kg°C * (65°C - 30°C). Calculate this to find the energy absorbed in joules.
How many grams of iron can be made form 119 g of Fe2S3 and 12.7 g C?
To determine the amount of iron that can be produced from 119 g of Fe2S3 and 12.7 g of C, we first need to calculate the molar mass of Fe2S3 and C. The molar mass of Fe2S3 is approximately 207.9 g/mol, and the molar mass of C is approximately 12.01 g/mol. Next, we calculate the moles of Fe2S3 and C by dividing the given masses by their respective molar masses. Then, we determine the limiting reactant by comparing the moles of Fe2S3 and C. Finally, we use the stoichiometry of the balanced chemical equation to calculate the theoretical yield of iron, which is approximately 42.4 grams.
How do you calculate q values?
Q value is calculated by taking the difference between the total mass-energy of the reactants and the total mass-energy of the products in a nuclear reaction. The formula for calculating Q value is: Q = (mass of reactants - mass of products) * c^2, where c is the speed of light in a vacuum (3.00 x 10^8 m/s).
What is Aspirin's chemical composition?
Aspirin is acetylsalicylic acid, SMILES O=C(Oc1ccccc1C(=O)O)C.
What is the percent composition by mass of C10H14O?
Percent composition means finding the total mass of each element in a molecule and then dividing it by the molecular mass. Use the molecular formula to help you find out how many atoms of each element you'll need. For carbon: 6 C x 12 g = 72 g For hydrogen: 10 H x 1 g = 10 g For oxygen: 5 O x 16 g = 80 g Molecular mass = C + H + O = 72 + 10 + 80 = 162 g Percent composition of C = 72/162 = 0.4444 = about 44.45% Percent composition of H = 10/162 = 0.061728395 = about 6.17% Percent composition of O = 80/162 = 0.49382716 = about 49.38%
What are the elements in aspirin?
Aspirin contain C,H,O.
What is the percent composition of C8H8O3?
To find the percent composition of C8H8O3, you will need to calculate the molar mass of the compound. C8H8O3 has a molar mass of 152 g/mol. To find the percent composition of each element: Carbon (C): (8 mol C / 152 g) * 100 = 52.6% Hydrogen (H): (8 mol H / 152 g) * 100 = 5.3% Oxygen (O): (3 mol O / 152 g) * 100 = 19.7% Therefore, the percent composition of C8H8O3 is approximately 52.6% carbon, 5.3% hydrogen, and 19.7% oxygen.
What is acetone's percent composition by mass?
%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.
What elements are in the compound aspirin?

How do i Calculate the change in thermal energy for a 10 piece of copper if it is cooled from 35 C to 21 C.?
You cannot. You need the mass of the piece of copper.
What is the literature value for the melting point of aspirin?
melting point- 136 degree C boiling point- 140 degree C
Calculate the percent nitrogen by mass in chlorophyll C55H72MgN4O5?
You would first calculate the atomic mass of chlorophyll, which would be 892.9 g/mol (I did not calculate this out, but looked it up b/c of the complexity of the calculation). Then find the molar mass of the Nitrogen part of the chlorophyll (4 mol *14.01 g/mol=56.04 grams). Then, take 56.04 grams/892.9grams= .06276, or 6.276% nitrogen by mass
