Sholpan [36]

Maalox is the trade name for an antacid and antigas medication used for relief of heartburn, bloating, and acid indigestion in which

4 ml contains

= 320mg of aluminum hydroxide

= 320mg of magnesium hydroxide

= 32mg of simethicone

recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day

given = 1 tea spoon = 5 ml

8 tea spoon = 40 ml

hence,

amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g

amount of magnesium hydroxide = 320/4 * 40 = 3.2 g

amount of simethicone = 32/4 * 40 = 320 mg = 0.32g

Iodine-131 decays with a half-life of 8.02

dlinn [17]

Radioactive material undergoes 1st order decay kinetics.

For 1st order decay, half life = 0.693/k

where k = rate constant

k = 0.693/half life = 0.693/8.02 = 0.0864 day-1

Now, for 1st order reaction,
k = $\frac{2.303}{t} X log \frac{initial.conc}{final.conc}$

Given: t = 6.01d, initial conc. = 5mg

∴0.0864 = $\frac{2.303}{6.01} X log \frac{5}{final.conc}$
∴ final conc. = 2.975 mg
