First, we will get the "n", the number of half lives, it is the elapsed time over the half life. In the problem, the time is measured in days, so we have
6/2 = 3
to get the ending amount of radioactive sample, we have
32g x (1/2)³ = 4 grams of radioactive sample ⇒ the amount left after 6 days
the answer equals to 29000
1 kg ------- 1000 g
? ----------- 146 g
146 x 1 / 1000
= 0.146 kg

Answer:</h2>
Numer of moles of Li₂CO₃:




Chemical Reaction:
2 LiOH(s) + CO₂(g) → Li₂CO₃(s) + H₂O(l)
- 1 mole of Li₂CO₃ is formed from 2 moles of LiOH.
Therefore, applying unitary method:
- 0.53473 mole of Li₂CO₃ is formed from 2 × 0.53473 = 1.06946 moles of LiOH.
