Answer: 2.25 grams

Explanation:

To find the remaining mass of an element, apply the following:

m0 = m/(2^n), where m0 is the remaining mass, m as the original mass and n as the number of half lives that have passed.

we have m, we just have to find n. To find n,

24/6 = 4 half lives have passed.

Applying the first formula,

m0 = (36)/(2^4) = 36/8 = 2.25 grams

Hope this helps, brainliest would be appreciated :)
