Jesse added 16 g of substance a to 4 g of substance b to obtain a certain amount of substance c. which statement is correct?

a)substance a and substance c have the same mass.
b)substance b and substance c have the same mass.
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.

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

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

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
