Chemistry calculate the mass of material in the given volume of solution

100cm3 of 0.25 mil dm-3 NH4NO3= 0.025 moles
100cm3 of 0.1 mol dm-3 AgNo3 =0.01 moles
25 cm3 of 1 mil dm-3 AgNo3=0.025
50cm3 of 0.2 mol dm-3 H2SO4=0.01
20cm3 of 0.1 mol dm-3 NaOH=0.02

Are those answers correct?

As far as I can see yes these answers are correct
Always follow the following instructions
Convert so that your volume and concentration are in equivalent units
Then multiply them together to find moles
