<u>Answer:</u> The moles of given hydrocarbon is 0.3 moles
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
We are given:
Given mass of ethane = 10.0 g
Molar mass of ethane = ![[(2\times 12)+(6\times 1)]=30g/mol](https://tex.z-dn.net/?f=%5B%282%5Ctimes%2012%29%2B%286%5Ctimes%201%29%5D%3D30g%2Fmol)
We need to divide the given value by the molar mass.
Putting values in above equation, we get:
In case of multiplication and division, the number of significant digits is taken from the value which has least precise significant digits. Here, the least precise number of significant digits are 1.
Hence, the moles of given hydrocarbon is 0.3 moles
Answer:
Mitochondria
Explanation:
Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.
The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of 3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.
In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.
The answer to this question is B
I would say to double the weight
Ignore the point, the majority of the points are along the trend line.
