Aspirins formula is C9H8O4
300 mg Aspirin (1 gram/1000 mg)(1 mole aspirin/180.154 grams)
= 0.00167 moles aspirin
Calculate the molecular weight of Aspirin, by adding up the atomic weights of the atoms that make it up. Then take the mass of the tablet (325mg, divide by 1000 too) and divide by the molecular weight you just got.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
To find the number of molecules in 0.325 g of aspirin, first calculate the number of moles: 0.325 g / 180.2 g/mol = 0.0018 moles. To find the number of molecules, use Avogadro's number (6.022 x 10^23 molecules/mol): 0.0018 moles x 6.022 x 10^23 molecules/mol = 1.0876 x 10^21 molecules.
To determine the number of moles of acetylsalicylic acid in the sample, we first need to calculate the molar mass of C9H8O4 (aspirin). Molar mass of C9H8O4 = (912) + (81) + (4*16) = 180.16 g/mol Next, we calculate the mass of acetylsalicylic acid in the sample: Mass of acetylsalicylic acid = 75.2% of 1 gram = 0.752 grams Finally, we find the number of moles using the formula: Number of moles = Mass / Molar mass Number of moles = 0.752 g / 180.16 g/mol ≈ 0.0042 moles Therefore, there are approximately 0.0042 moles of acetylsalicylic acid in the sample.
16 grams of oxygen how many moles is 0,5 moles.
No formula, just dimensional analysis and ratios. Aspirin is C9H8O6 300 mg C9H8O6 (1 gram/1000 milligrams)(1 mole C9H8O6/212.154 grams) = 1.41 X 10^-3 moles aspirin just get milligrams up to grams and divide that by the molar mass

2.77*10^-3 mol
Calculate the molecular weight of Aspirin, by adding up the atomic weights of the atoms that make it up. Then take the mass of the tablet (325mg, divide by 1000 too) and divide by the molecular weight you just got.
300mg is about 0.0106 ounces.
1.50 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 1023/1 mole C)= 8.13 X 1024 carbon atoms===================
2.6 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 10^23/ 1mole C) = 1.4 X 10^25 atoms of carbon
To find the number of molecules in 0.325 g of aspirin, first calculate the number of moles: 0.325 g / 180.2 g/mol = 0.0018 moles. To find the number of molecules, use Avogadro's number (6.022 x 10^23 molecules/mol): 0.0018 moles x 6.022 x 10^23 molecules/mol = 1.0876 x 10^21 molecules.
There are approximately 0.01058 ounces in 300 milligrams (mg).

Aspirin : 180.157 g/mol (according to Wikipedia - props) (0.325g)/(180.157g/mol) = 0.0018mols Unit logic : (g )/ (g/mol) {multiply by reciprocate} = (g) x (mol/g) {"(g/g)= 1} = 1mol = mol
