Answer : The amount of bark needed is, 8000 kilogram
Explanation :
As we are given 1 kilogram of bark can produce about 0.015 kilogram of paclitaxel. Now we have to determine the amount of bark needed to make 120 kilogram of paclitaxel.
As, 0.015 kilogram of paclitaxel produced from 1 kilogram of bark
So, 120 kilogram of paclitaxel produced from kilogram of bark
Therefore, the amount of bark needed is, 8000 kilogram
You can solve this problem by using ratio. The ratio of weight of bark and paclitaxel is 1 : 0.015. So when you need 120 kilograms of paclitaxel, you need 120/0.015=8000 kilograms of bark.
In an atomic model that includes a nucleus, the negative charge correlates to the electron and is located outside of the positively charged nucleus. It is found in a given region, where there is a probability of electrons to be found called the electron cloud.
