Help please If you have 100 grams of a radioactive isotope with a half-life of 10 years:
Part A How much of the isotope will you have left after 10 years?
Part B. How much of the isotope will you have left after 20 years?
Part C. How many half-lives will occur in 40 years?
fill in the chart

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
