C)The mass of substance C is twice the mass of substance A.
D)The mass of substance C is five times the mass of substance B.

Respuesta :

Answer;

D)The mass of substance C is five times the mass of substance B.

Explanation;

Mass of substance A = 16 g

Mass of substance B = 4 g

Therefore;

The mass of substance C = Mass of substance A + Mass of substance B

                                          = 16 g + 4 g

                                          = 20 g

This mass of 20 g of substance C is five times the mass of substance B
