You are performing an experiment combining two substances in a closed container. You first pour 350 mL of substance one followed by 430 mL of substance two. A chemical reaction occurs. Choose the equation below that would best explain the total mass of the combined substances.

• 430 mL - 350 mL = 80 mL

• 350 mL x 430 mL = 780 mL

• 350 mL + 430 mL = 780 mL

• 780 mL - 430 mL = 350 mL
