Potassium has a half-life of 12 hours. What fraction of a 100g sample is left after 48 hours

EastWind [94]

Answer:

After 48 hours amount left = 6.25 g

Explanation:

Given data:

Half life of potassium = 12 hours

Total mass = 100 g

Mass left after 48 hours = ?

Solution:

Number of half lives passed:

Number of half lives = Time elapsed / half life

Number of half lives = 48 hours/ 12 hours

Number of half lives = 4

At time zero = 100 g

At first half life = 100 g/ 2 = 50 g

At 2nd half life = 50 g/2 = 25 g

At 3rd half life = 25 g/2 = 12.5g

At 4th half life = 12.5 g/2 = 6.25 g

The aspect from which a sample is drawn is known as the

PolarNik [594]

We use samples to perform experiments. When sampling, we take test subjects from a larger group often known as "population" or at times "universe".

Sampling is a term we use to describe the process of selecting a small representitive group from a larger population. Sampling can often be divided in its simplest form into:

Random Samples
Non-Random Samples.

Which as their names imply, represent first a sample that is chosen by not specific method and whose probability is equal for the entire population, and secondly a sample chosen based on specific parameters.

Sampling can then become more complex, being divided into more complex methods such as:

Systematic sampling
Stratified sampling
Cluster sampling

etc.

The one thing all of the sampling methods have in common is the fact that they will all draw their samples from one place. This place or aspect from which samples are drawn is known as the population group or sometimes coined as the universe, to represent the group in its entirety.

How primates and hominids are different?

dem82 [27]

The difference between primates and hominids: a primate refers to members of the ORDER Primate which includes monkeys, lemurs and apes. A hominid is a member of the FAMILY Hominidae (great apes) which includes gorillas, chimpanzees, orangutans, and us humans. A hominid is just a specific group of primate. Meaning, since the order primate composes of monkeys, lemurs and apes, the hominid is just a certain kind of primate belonging to the "ape" category, which differentiates it from other primates who belong to the "monkey" or "lemur" subtype.

I hope this helps.
