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
You can calculate the mass composition of carbon (C), hydrogen (H), and oxygen (O) in aspirin (C9H8O4) by determining the molar mass of each element and then calculating the percentage composition based on their respective masses. The molar mass of carbon is 12.01 g/mol, hydrogen is 1.008 g/mol, and oxygen is 16.00 g/mol. Sum the masses of each element in a molecule of aspirin to find its molar mass, then calculate the mass percentage of each element.

What is the literature value for the melting point of aspirin?
The literature value for the melting point of aspirin is approximately 135-136 degrees Celsius.
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.
Atom economy of aspirin?
The atom economy of aspirin synthesis is relatively high, around 90%. This means that about 90% of the reactant atoms are found in the final product, while only around 10% are considered waste. This efficiency is one of the reasons why the synthesis of aspirin is considered to be environmentally friendly.
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).
Does it mean to multiply the mass of anything with speed of light squared?
E=MC(squared) According to einstein, matter is made of energy, if you multiply the mass with c, you get the energy composition of the said body in a said moment in time.
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?
To find the percent composition by mass of C10H14O, we need to calculate the molar mass of the compound, then divide the molar mass of each element by the total molar mass and multiply by 100. Molar mass C: 12.01 g/mol, H: 1.01 g/mol, O: 16.00 g/mol Total molar mass = (1012.01) + (141.01) + 16.00 = 150.24 g/mol Percent composition C = (1012.01/150.24) * 100 Percent composition H = (141.01/150.24) * 100 Percent composition O = (16.00/150.24) * 100
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 are the elements in aspirin?
Aspirin contain C,H,O.
What is acetone's percent composition by mass?

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.
Calculate the percent nitrogen by mass in chlorophyll C55H72MgN4O5?
To calculate the percent nitrogen by mass in chlorophyll, first find the molar mass of nitrogen: 14.01 g/mol. Then calculate the molar mass of the entire molecule using the atomic masses of C, H, Mg, N, and O. Finally, divide the mass of nitrogen by the total molar mass of the compound and multiply by 100 to get the percentage. In this case, the percent nitrogen by mass in chlorophyll is approximately 1.53%.
