Well, it depends on the label...

Define

  • the total number of calories, #"Cal"#, as #q_(Cal)#
  • the number of calories per container as #barq_(Cal)# in terms of #"Cal/container"#
  • the number of servings as #N_(Serv)#
  • the serving size in terms of #"g/serving"# as #m_(Serv)#

Then by simple unit conversion,

#8 cancel"servings" xx "43 g"/cancel"1 serving" = "344 g/container"#

And thus,

#color(blue)(q_(Cal)) = "190 Cal"/cancel"container" xx cancel"1 container"/"344 g"#

#=# #color(blue)("0.522 Cal/g")#

In general,

#barul|stackrel(" ")(" "q_(Cal) = barq_(Cal)/(N_(Serv)m_(Serv))" ")|#
