M = molar mass (g/mol) - take this from the Periodic Table
m = mass (g) - we can measure this
n = number of moles (mol) - this might be given in the problem]]> 2020-10-08 07:02:43 UTC https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812922664 Calculating concentration kwheglund https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812930752 C = n/V
C = concentration (mol/dm3) - this might be given in the problem
n = number of moles - use M=m/n to calculate for this
V = volume (dm3) - we can measure this]]> 2020-10-08 07:06:53 UTC https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812930752 Naming Exercise kwheglund https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812940429 2020-10-08 07:12:00 UTC https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812940429 kwheglund https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812945988 2020-10-08 07:14:54 UTC https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812945988 Ionic Compounds Exercise kwheglund https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812952767 2020-10-08 07:18:17 UTC https://padlet.com/kwheglund/16pcsel4upfpt3sq/wish/812952767
