How many moles are in 0.06 grams of iron

Chemistry
1 answer:
Eva8 [605]3 years ago
3 0
No of mole = reacting mass/ molar mass

No of mole = 0.06/56

No of mole = 0.00107mol....

Or...

1mole of iron contain 56gmol¯¹
:-x mole is contained in 0.06g

Porata
And you'll have..

x = 0.06/56

x = 0.00107mol.....

How does scarcity impact society
g100num [7]

Answer:

a market/society is dictated by supply and demand and scarify affects the supply of a product because if something is more scarce/rare then usually there is a higher demand and a higher price. This impacts society because it affects the price of things and how much people are willing to give for it

How many molecules of propane were in the erlenmeyer flask? Avogadro's number is 6. 022 × 10^23 molecules/mol
Ede4ka [16]

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}

<h3>What is erlenmeyer flask?</h3>
  • 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.

<h3>What purpose does an Erlenmeyer flask serve?</h3>
  • 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.
