The mass of neptune is about 1.03x10^23 metric tons. The mass of the sun is about 1.998x10^27 metric tons. About how many times the mass of Neptune is the mass of the sun? Give answer in scientific notation.
The mass of the sun is about___times the mass of Neptune. Round to the nearest thousandth as needed.
Online "*" is used to indicate multiplication, because "x" may be confused with an unknown.
(1.998*10^27)/(1.03*10^23) = 1.940*10^4
To find how many times the mass of Neptune is the mass of the sun, we need to divide the mass of the sun by the mass of Neptune.
Given information:
Mass of Neptune = 1.03x10^23 metric tons
Mass of the sun = 1.998x10^27 metric tons
We can set up the equation:
Mass of the sun / Mass of Neptune = x
Plugging in the values:
1.998x10^27 metric tons / 1.03x10^23 metric tons = x
To divide the numbers in scientific notation, we divide the coefficients and subtract the exponents:
(1.998 / 1.03) x 10^(27 - 23) = x
(1.938) x 10^4 = x
Therefore, the mass of the sun is about 1.938x10^4 times the mass of Neptune.
Rounding to the nearest thousandth, the final answer is 1.938x10^4.
