what is the molarity of a solution in which 0.412 kg copper (2) Nitrate trihydrate is dissolved in enough water to make 125cm3 of solution ?

Molar mass of copper(ii)sulphate (CuSO4)=(63.5+32+4×16)g/mol=159.5g/mol

2. Molarity,S=W/MV

= 23g/159.5g/mol×0.8L

= 0.18M

3.Molar mass of iron(iii)nitrate[Fe(NO3)3]=[56+(14+3×16)3]g/mol=242g/mol

W=SMV

= 0.3M×242g/mol×0.4L

= 0.003g

= 3 mg

d.) circle motion requires a force to give it a centripetal acceleration.
