Starter question
How many particles are there in 10g of CaCO3?
How many moles are there in 25g HNO3
Copy and Complete
There are ___ subatomic particles inside an atom. The protons
and _________ are found in the ______ of an atom. They both
have a mass of ___ however the _________ has ____ charge and
the proton has a charge of _____.
The ____________ are found _________ the nucleus. They are
extremely light and therefore we treat them as having ____
_____. They have a charge of _____.
The majority of an atom is made up of __________ _________
Add to foldable
Particles to moles
Calculate the number of moles of zinc that contain 4.50x1024
atoms
1 mole = 6.02x1023 atoms.
4.50x1024=
4.50x1024 moles
6.02x1023
= 7.48moles
If we want to convert this to g, then we simply now use our
method for going from moles to g.
1 mole Zn= 65.38g
7.48 moles = 65.38 x 7.48= 489g
Complete the following questions.
p316- 12
p318- 13, 14
p323- 27- 29
p324- 30
p326- 32-35
Now use your reference tables and calculators to complete the
quiz on socrative.
