Aspirin is the common name for acetyl salicylic acid, cgh804. one tablet contains 0.325 g of aspirin. how many moles of aspirin is
this?

0.0018 moles

Explanation:

Given data:

mass of aspirin= 0.325 g

molar mass of aspirin= 180.1589 g/mol

number of moles=?

Formula:

number of moles= mass in gram/ molar mass (g/mol)

Solution:

now we will put the values in given formula:

number of moles of aspirin= mass of aspirin/ molar mass of aspirin

number of moles= 0.325 g/ 180.1589 g/mol

number of moles = 0.0018 mol

Mole:

Mole is the unit of amount in chemistry. it is SI unit and represented by "mol".

Example;

one mole of hydrogen has a mass of 1.008 g and contain 6.022× 10∧23  atoms.

58.5 moles acetyl salicylic acid

Explanation:

Molar mass of acetyl salicylic acid, C9H804

C= 12g/mole ⇒ 9*12 = 108g/mole

H=1g/mole ⇒ 8*1 =8

O=16g/mole ⇒ 4*16 =64g/mole

⇒108+8+64 = 180g/mole

Moles acetyl salicylic acid:

mole = mass * Molar mass

moles acetyl salicylic acid = 0.325g * 180g/mole = 58.5 moles acetyl salicylic acid

This aspirin, of 0.325g, has 58.5 moles of acetyl salicylic acid
