Calculate the volume (mL) of 1.0 M metal nitrate solution required to prepare 3.0 g of CaCO3. Again, using the balanced chemical equation you should be able to relate the moles of pigment to the moles of metal nitrate and from that calculate the volume of 1.0 M metal nitrate solution required. Balanced equation: Ca(NO3)2 (aq) + K2CO3 (aq) ↔ CaCO3 (s) + 2KNO3 (aq)
