The mass of Pluto is about 1.31 x 10^19 metric tons. The mass of the sun is about 1.998x10^27 metric tons. About how many times the mass of Pluto is the mass of the sun? Give answer in scientific notation.
Is this correct?
1.53x10^8
correct
Thanks. You are such an ego booster. I am doubting how much I really know.
no problem. you're doing very well!!
To determine how many times the mass of Pluto is the mass of the sun, we need to divide the mass of the sun by the mass of Pluto.
First, let's convert the mass of Pluto to scientific notation:
1.31 x 10^19 metric tons.
Next, let's convert the mass of the sun to scientific notation:
1.998 x 10^27 metric tons.
Now, divide the mass of the sun by the mass of Pluto:
(1.998 x 10^27) / (1.31 x 10^19)
To divide two numbers in scientific notation, subtract the exponents and divide the coefficients:
(1.998 / 1.31) x 10^(27-19) = 1.525 x 10^8.
Therefore, the mass of the sun is about 1.53 x 10^8 times the mass of Pluto.
Regarding your answer, 1.53 x 10^8 is indeed the correct result. Great job!
