Convert all the masses to the same unit and pick the product with the highest mass. Let's change all the masses to grams ( g ) To change kilogram (kg) to gram, you must multiply by 1000 To change milligram (mg) to gram, you must divide by 1000 Product X mass =0.05kg=0.05×1000g=50g Product Y mass =50mg=
50
1000
=0.05g Product Z mass =500g Product W mass =0.05g Product Y and W have the same mass, 0.05 g .
