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 1000To change milligram (mg) to gram, you must divide by 1000Product $X$ mass $=0.05\,\mathrm{kg}=0.05 \times 1000\,\mathrm{g}=50\,\mathrm{g}$Product $Y$ mass $=50\,\mathrm{mg}=\;\frac{50}{1000}=0.05\,\mathrm{g}$Product $Z$ mass $=500\,\mathrm{g}$Product $W$ mass $=0.05\,\mathrm{g}$Product $Y$ and $W$ have the same mass, 0.05 g .
