Answer 1

CaCO3        M=40+12+3.16=100
                  100gCaCO3---------1mol CaCO3


HNO3          M=1+14+3.16=63
                  63g HNO3--------------1mol HNO3

CuSO4        M=64+32+4.16=160
                     160g CuSO4------------1mol CuSO4

CO2            M=12+2.16=44
                    44 g CO2-----------1mol CO2

AgNO3        M=108+14+3.16=170
                 170g AgNO3-----------1mol AgNO3
