Question

How many molecules of propane were in the erlenmeyer flask? Avogadro's number is 6. 022 × 10^23 molecules/mol

Answer 1

3.74×$10^{21}$

3.74 ×$10^{21}$ molecules of propane were in the erlenmeyer flask.

number of moles of propane can be calculated as moles of propane.

mass of propane =  0.274 g

molar mass of propane = 44.1

So this gives us the value of 6.21×$10^{-3}$ moles of propane

No one mole of propane As a 6.0-2 × $10^{23}$

so, 6.21 ×$10^{-3}$ × 6. 022 × 10^23

= 3.74 ×$10^{21}$

Therefore, molecules of propane were in the erlenmeyer flask is found to be 3.74 ×$10^{21}$

What is erlenmeyer flask?

• A laboratory flask with a flat bottom, a conical body, and a cylindrical neck is known as an Erlenmeyer flask, sometimes known as a conical flask or a titration flask.
• It bears the name Emil Erlenmeyer after the German chemist.

What purpose does an Erlenmeyer flask serve?

• Liquids are contained in Erlenmeyer flasks, which are also used for mixing, heating, chilling, incubating, filtering, storing, and other liquid-handling procedures.

• For titrations and boiling liquids, their sloped sides and small necks make it possible to whirl the contents without worrying about spills.
