First, we have that Chance has $4 in quarters. We know that one quarter equals 25 cents, then for $4 we have:
![\begin{gathered} 4\text{ dollars = 400 cents} \\ \Rightarrow(400)/(25)=16 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wlpqjqjfnub91owq7xt2esaaqd71d8fpyw.png)
Then, Chance has 16 quarters, each one weighs 5.67g, then:
![(16)\cdot5.67=90.72g](https://img.qammunity.org/2023/formulas/mathematics/college/ybuhpp5uuhlh7rwjygxnwbw0d60b96mcr7.png)
Now, Blake has $6 in dollar coins, each weighs 8.1g, then:
![(6)(8.1)=48.6g](https://img.qammunity.org/2023/formulas/mathematics/college/3r4yyoy6j6clcfkti4c9eau4gci49phwjw.png)
therefore, Blake has 48.6g of the coins, Chance has 90.72g of the coins.
Chance has the greatest mass.
