2.00 mg / 128.0 mg = 0.015625. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. How much of a substance will be left after a certain amount of time? One format involves calculating a mass amount of the original isotope. We use the relalation n t = 1 2 t t 1 / 2 n o.

The answers are at the bottom of this page, upside down. If one had 6.02 x 10 23 atoms at the start, how many atoms would be present after 20.0 days? How much of a 10 g sample will be left after 0.003 seconds? After 24.0 days, 2.00 milligrams of an original 128.0 milligram sample remain.

From n t = 1 2 t t 1 / 2 n o. Has a half life of ???3??? After 24.0 days, 2.00 milligrams of an original 128.0 milligram sample remain.

2.00 mg / 128.0 mg = 0.015625. (1/2) n = 0.015625 n log 0.5 = log 0.015625 n = log 0.5 / log 0.015625 n = 6 = 5 log 2 log 150 120. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed? Decomposition of a certain substance y at 45°c was found to be zero order.

We use the relalation n t = 1 2 t t 1 / 2 n o. Has a half life of ???3??? The answers are at the bottom of this page, upside down.

2.00 Mg / 128.0 Mg = 0.015625.

Using the equation below, we can determine how much of the original isotope remains after a certain interval of time. Decomposition of a certain substance y at 45°c was found to be zero order.
