Answer:
To find the number of moles of sulfuric acid in 100 cm³ of a 2.00 mol/dm³ solution, we need to use the formula:
Number of moles
=
Concentration
×
Volume (in dm
3
)
Number of moles=Concentration×Volume (in dm
3
)
First, we convert 100 cm³ to dm³:
Volume
=
100
1000
dm
3
=
0.1
dm
3
Volume=
1000
100
dm
3
=0.1 dm
3
Then, we use the given concentration:
Concentration
=
2.00
mol/dm
3
Concentration=2.00 mol/dm
3
Now, we can calculate the number of moles:
Number of moles
=
2.00
mol/dm
3
×
0.1
dm
3
Number of moles=2.00 mol/dm
3
×0.1 dm
3
Number of moles
=
0.2
moles
Number of moles=0.2 moles
So, there are 0.2 moles of sulfuric acid in 100 cm³ of a 2.00 mol/dm³ solution.
