Idk i just need to ask a question
Hi,
the answer should be the last one, ‘neither accurate nor precise’.
The values are quite different from one another and not close to the actual value.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
<span>The molecular formula for Copper(II) Sulfate is CuSO4. 1 mole is equal to 1 moles Copper(II) Sulfate, or 159.6086 grams.I hope this is right </span>
1.694 L
Explanation:
First, solve for the number of moles of HCl in a 450-ml 3.2M solution:
# of mol HCl = (3.2 mol HCl/L)(0.450 L)
= 1.44 mol HCl
The molarity M is given by
M = (# of moles)/(volume in L)
Solving for the volume,
V = (# of moles)/M
= (1.44 mol HCl)/(0.85M)
= 1.694 L
Therefore, the 3.2M HCl solution must be diluted until its volume becomes 1.694 L.
