Answer: The current common definition of an acid and a base is based upon how the substance releases or attracts hydrogen ions (H+). Acids release H+ ions that can turn neutral molecules into positively charged ions, while bases can attract H+ ions from neutral molecules to produce negatively charged ions.
Explanation:
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.
Answer:
Density = mass/ volume
Explanation:
57.4g / 11.5cm3 = 4.991304(g/cm)
round to sig figs = 5.00(g/cm)
