Answer :
Note that 1 qt = 946.35 ml
To convert 8.9 qt to ml, multiply it with the conversion above,
that will be :
[tex]8.9\times946.35=8422.515[/tex]In multiplying significant figures, the least number of significant figures will follow.
In this case, 8.9 has 2 significant figures, so the answer must be in 2 significant figures also.
That will be :
[tex]8.4\times10^3[/tex]The answer is 8.4 x 10^3 ml
