Question

In nuclear fusion, about 0.60% of the mass of the fusing substances is converted to energy. What mass in grams is converted into energy when 22 kilograms of substance undergoes fusion?

Answer 1

Answer: 13.2 grams .

Step-by-step explanation:

We are given that ,

In nuclear fusion, about 0.60% of the mass of the fusing substances is converted to energy.

When 22 kilograms of substance undergoes fusion , then the mass of the fusing substances is converted to energy.  = 0.06% of (22 kilograms)

Convert % into decimal by dividing it by 100 and replace 'of ' by multiplication operator (x) , we get

Mass of the fusing substances is converted to energy.  = $\dfrac{0.06}{100}\times22=0.0132\ kg$

Since 1 kilogram = 1000 grams.

Therefore , Mass of the fusing substances is converted to energy.  =$0.0132\times1000 =13.2\ g$

Hence,  13.2 grams of mass  is converted into energy when 22 kilograms of substance undergoes fusion.
