What is the molar mass of salicylic acid?
138.121 g/mol Salicylic acid/Molar mass
How do you calculate 1 mole?
If you know the particles, moles, or grams of a substance, you can calculate the other two measurements by using the following equation: 1 mole = 6.022 × 1023 particles/mol = formula weight expressed in grams. From the Periodic Table, the mass of one atom of chromium is 51.9961 amu.

How do you calculate moles of salicylic acid?
question 1
- Mass of Salicylic Acid Used (mock value) = 276.24 g.
- Molar Mass of Salicylic Acid = 138.12 g.
- Moles of Salicylic Acid = (1)/(2) = 276.24/138.12 = 2.000 moles.

What is 1 mole of a substance?
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
