Answer:
B. C, A, B
Explanation:
We can measure the age of an artifact by comparison of the activities a living sample with that of the artifact. This is so because the activity of the living sample represents the original activity of the artifact.
So, the steps involved in determining the age of an artifact is to measure the ratio of the parent and daughter nuclei. Then we use the half life of carbon to find out how many half lives have passed. Using this number of half lives that has passed, we can compute the age of the object.
Answer:
<h3>The answer is 2.12 atm</h3>
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we are finding the new pressure
So we have
We have the final answer as
<h3>2.12 atm</h3>

<u>Given data:</u>
Volume of solution measured = 0.0067 L
<u>To determine:</u>
The number of significant figures
<u>Explanation:</u>
Significant figures are the number of digits that accurately describe a measured value.
As per the rules:
All non-zero digits are significant
Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant
Hence in the given value 0.0067, there are 2 significant figures (6 &7)
The density of the unknown material is 0.213 ml/g
<h3>
Apparent density of the unknown material</h3>
The apparent density of the unknown material is calculated as follows;
Volume of the unknown substance = 126 ml - 102 ml = 24 ml
Density of the unknown substance = mass/volume
Density of the unknown substance = 24 ml / 112.6 g
Density of the unknown substance = 0.213 ml/g
Thus, the density of the unknown material is 0.213 ml/g
