Cross multiply
18 / X = 2.4 / 28
so
18 * 28 = X (2.4)
and that becomes
504 = X * 2.4
then divide by 2.4
X = 210
Answer:
22.1 grams
Step-by-step explanation:
At the end of each minute, (1 -17.1%) = 82.9% of the element remains. At the end of 19 minutes, the quantity has been multiplied by that value 19 times, so the remaining amount is ...
(780 g)(0.829^19) ≈ 22.1 g
After 19 minutes 22.1 grams remain.
