Answer:
7.534g ring is heavier, by 2.234g
Step-by-step explanation:
Note: mg =
[tex] {10}^{ - 3} grams[/tex]
[tex]5300mg = ( \frac{5300}{ {10}^{3} } )g \\ = ( \frac{5300}{1000} )g \\ = 5.3g[/tex]
From here we can see Ring A (7.534g) is heavier than Ring B(5,300mg)
Difference in Mass = 7.534g - 5.3g
= 2.234g
