Noah made 12 kg of trail mix for his family's hiking trip. his family ate 8600 g of the trail mix on the hiking trip how many grams of trail mix did noah have left

The amount of trail  mix that is left in grams is:

                      3400 grams

The amount of trail mix that is made by Noah is:  12 kg

We know the conversion that:

           1 kg=1000 grams

Hence,  12 kg=12000 grams

and His family ate 8600 g of the trail mix on the hiking trip.

This means that the amount of trail mix that is left is:

 Amount made-Amount that is eaten by his family.

=  12000-8600  grams

=  3400 grams

          Hence, the answer is:

                   3400 grams
