There are 27 x 10⁷ cells in total for the given conditions of cell culture.
Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.
Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-
75 x 12 = 900 ml
Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-
900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells

Sunscreens contain chemical ingredients in their compositions, such as avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate, which have been linked to health problems such as hormonal disruptions, cancer, as well as liver and kidney changes.
<h3>What is oxybenzone, octocrylene, and homosalate bad for?</h3>
Oxybenzone, octocrylene, and homosalateto protect from UVA also penetrates deep into the skin. The penetration into the human body can cause several problems in human health such as
- allergic reactions
- cell mutation
- deregulation of hormonal processes,
- etc.
With this information, we can conclude that Oxybenzone, octocrylene, and homosalateto is considered a hazardous eye irritant and, as an allergen, is also known to cause skin allergies.
