The Mole Bridge

 

How to use this mole bridge:

1. You are only allowed to go from left to right.

2. The great divide side, you will divide. 

3. On the Rabittville, side you will be multiplying (rabbits multiply).

Those are the rules

 

 

Mass to moles- divide by the molar mass

36.0g H2O

 

36.0g H2O X

1 mole

=2.00 moles water

18.0g

66.0g CO2

 

66.0g CO2 X

1 mole

=1.50 moles CO2

44.0g

Moles to mass- multiply by the molar mass

5.0 Moles of He atoms

 

5.0 Moles X 4.00g =20.0g He atoms
1 mole
30.0 moles of H2

 

30.0 moles X 2.00g =60.0g of H2
1 mole

Moles to particles-multiply by Avagodro's Number

5.0 Moles of Fe atoms

 

5.0 Moles X 6.021023 =3.0 x 1024 Fe atoms
1 mole
30.0 moles of H2

 

30.0 moles X 6.021023 =1.8 x 1025 H2 molecules
1 mole

Particles to moles-divide by Avagodro's Number

1.8 x 1024 Donuts

 

1.8 x 1024 X

1 mole

=3.0 moles Donuts

6.021023

3.0 x 1025 O2 molecules

 

3.0 x 1025 X

1 mole

=50 moles O2 molecules

6.021023

5.4 x 1022 Molecules of Glucose

 

5.4 x 1022 X

1 mole

=0.090 moles of Glucose

6.021023

Vol. at STP to moles-divide by 22.4L

44.8L of Helium at STP

 

44.8L He X

1 mole

=2.00 moles of Helium

22.4L

Moles to Volume at STP-multiply by 22.4L

2.5 moles of H2

 

2.5 moles X 22.4L =  56.0L of H2
1 mole
