Jill and Susan violated safety procedures by not properly listening and/or reading over the instructions to know all the materials, steps, and equipment they need for the lab. Hope this helps!
Valence election configuration is the electrons in the shell that equal to 8. it what forms chemcial bonds. Electron configuration is distribution of elections of an atom.
Answer : 19.9 mL
Explanation : We have the moles of Calcium chloride and the weight of it as 1.28 g,
Here, molarity has to be related with the volume so, 0.580 M = 0.580 mol/L
so now in 1.28 g there will be : 1.28 X (1 g / 111 mol of calcium chloride) = 0.01153 mol
Now, we can find out the volume from this;
0.01153 mol X (1 L / 0.580 mol) X (1000 mL / 1 L) = 19.9 mL
Hence, the volume will be 19.9 mL
(1) An alpha particle has the greatest mass.
Hope this helps~
