Which object would a geologist date using carbon-14 dating?

2 answers:

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. ... Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies. Carbon-14 is also passed onto the animals that eat those plants.

The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon.
The age detection of the ancient objects are very tough,due to no records are available about the objects.
That's why scientists use carbon-14 dating process.
In this picture, the only object that contains organic material is the animal skull, thus it is the only one that can be dated with this method.

A chemistry student needs 10.00 g of isopropenylbenzene for an experiment. He has available 120. g of a 42.7% w/w solution of is

Vanyuwa [196]

Answer: The mass of solution that the chemistry student should use is 23.4 grams

Explanation:

We are given:

Available mass of isopropenylbenzene = 120. g

Amount of isopropenylbenzene needed by chemistry student = 10.00 g

42.7 % (w/w) solution of isopropenylbenzene.

This means that 42.7 grams of isopropenylbenzene is present in 100 grams of solution.

To calculate the mass of solution for given needed of isopropenylbenzene, we apply unitary method:

For 42.7 grams of isopropenylbenzene, the amount of solution needed is 100 grams

So, for 10.00 grams of isopropenylbenzene, the amount of solution needed will be = $\frac{100}{42.7}\times 10=23.4g$

Hence, the mass of solution that the chemistry student should use is 23.4 grams
