So from 3:16; 16/3=5.33 (recurring) then to solve for the mass of zinc you divide 320 by 5.33 (recurring) to give you 60g ... the mass of zinc

Since there is 320 grams of copper, than 16 multiplied by 20 will be 320. So then you have to multiply 3 times 20 which is 60. So
3:16 multiplied by 20 will be 60:320.

ANSWER:
60 parts zinc. Hope this helped. Have a great day! A brainliest and (or) thank you is always appreciated. Goodbye!

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
