to convert any value in miles per second to meters per second, just multiply the value in miles per second by the conversion factor 1609.344. So, 10095 miles per second times 1609.344 is equal to 1.625 × 107 meters per second.
According to Avogadro constant 1 mole = 6.02 x 10^23 what about 9.25 x10 ^21
that is 1 mole x ( 9.25 x10 ^21) / (6.02 x10^23) = 0.0154 moles
