SOLUTION: Current evidence indicates 22% of the mass of an asteroid that crashed into Earth turned to dust and resulted in about 0.022 {{{g/cm^2}}} of the Earth’s surface being covered.

Question 1152500: Current evidence indicates 22% of the mass of an asteroid that crashed into Earth turned to dust and resulted in about 0.022 of the Earth’s surface being covered.
a) If the asteroid had a density of about 2.0 and the area of the Earth is 510.1 trillion , calculate the mass of the asteroid.

.022 ( g / cm2 ) x ( 10^4 cm2 / 1 m2 ) = 220 g / m2
----------
510.1 X 10^12 ( m^2 ) x 220 ( g / m2 ) = 112222 x 10^12 ( g )
112222 x 10^12 ( g ) = 1.12222 x 10^17 ( g )
----------
Let = the mass of the asteroid

g
---------------------------
I don't think the density of the asteroid is needed
