Problema Solution
the mass of mars is about 6.421*10(20) metric tons.the mass of the sun is about 1.998*10(27) metric tons. about how many times the mass of mars is the mass of the sun? give answer in scientific notation
Answer provided by our tutors
Mass of mars = 6.421*10(20)
Mass of Sun = 1.998*10(27)
Let us assume the mass of sun is x times of mass of mars
Then, 1.998*10(27) = x*6.421*10(20)
=> x = 1.998*10(27)/6.421*10(20)
= 19.98/6.421 * 10(26-20) = 3.112*10(6)
