Answer:
1dm = 10cm
1dm3 = 10cm x 10cm x 10cm = 1000cm3
1L = 1000cm3
so 1litre = 1dm3
4 moles in 2 dm3
= 2 moles in 1dm3 = 2moles in 1L = 2M
1L = 1000cm
0.3 moles in 200cm3 =
200cm3 = 0.2L
so 0.3 moles in 0.2 L = 1.5 moles in 1 L = 1.5M
(I have tried to simplify and show why 1dm3 = 1L)
I hope this helps you understand!
