2 moles
Explanation:
Given parameters:
Mass of Sb = 243.52g
Unknown:
Number of moles = ?
Solution:
The number of moles of any substance can be calculated using the expression below:
Number of moles =
Molar mass of Sb = 121.76g/mol
Now input the parameters:
Number of moles = = 2 moles

<span>You have the answer and you don’t even know it. Just take the inverse of what one electron weights in grams (9.11E-28) to get the number of electrons in one gram. You should get an astonishing large number (1.10E+27). Just in case you do not recognize the notation it is scientific notation as a calculator would write it.</span>
The mixture can be separated into three separate components by using a centrifuge and a separating funnel.
A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.
-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.
- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.
- The remaining liquid on the separating funnel can be collected in a different flask.
-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.
- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube
Each mole of C₂H₄ produces 2 moles of H₂O
Moles of H₂O produced = 2 x 6.1
= 12.2 moles
Each mole of gas occupies 22.4 L at STP
Volume of H₂O = 22.4 x 12.2
= 273.28 Liters
