#4# grams

Explanation:

If a balloon was #4# grams, and after inflating it by adding air, it became #8# grams, knowing that you want to find the mass of the air in the balloon, subtract the initial mass of the balloon from its final mass. This will give you the mass of the air in the inflated balloon.

#8color(white)(i)"grams"-4color(white)(i)"grams"#

#=color(green)(|bar(ul(color(white)(a/a)4color(white)(i)"grams"color(white)(a/a)|)))#

#4# grams.

Explanation:

#"mass" _ "total" = "mass" _ "balloon" + "mass"_"air"#

#=> "mass" _ "air" = "mass" _ "total" - "mass" _ "balloon"#

#:. "mass" _ "air" = 8"g" - 4"g" = 4"g"#
