Answer:

a. #3.3712*10^(23)#

b. #0.04165g#

Explanation:

a. #a=nL#, where:
- #n# = number of moles (#mol#)
- #L# = Avogradro's constant (#~~6.02*10^(23)# #mol^(-1)#)
- #a# = number of molcules/ions/atoms

#a=(6.02*10^(23))(0.56)=3.3712*10^(23)#

b. #m/M=n#, where:

  • #m# = mass (#g#)
  • #M# = molar mas (#g# #mol^(-1)#)
  • #n# = number of moles (#mol#)

#m=Mn=(4.25*10^(-4))(2(1)+32+4(16))=0.04165g#
