The following numbers are recorded by scientific counting method: (1) the earth is about 150 million kilometers away from the sun. (2) the reserves of coal on the earth are estimated to be more than 15 trillion tons Write down the following numbers by scientific counting method: (1) The earth is about 150 million kilometers away from the sun (2) The reserves of coal on earth are estimated to be more than 15 trillion tons (3) The mass of the moon is about 7 340 000 (4) The number of stars in the Milky way is about 160 million tons (5) The radius of the earth's orbit around the sun is about 149 000 km (6) There are about 25 million molecules in 1 cm of air

1) The earth is about 150 million kilometers away from the sun = 1.5 * 10 ^ 8 km (2) the reserves of coal on the earth are estimated to be more than 15 trillion tons (1.5 * 10 ^ 13 tons) (3) the mass of the moon is about 7 340 million = 7.34 * 10 ^ 15 (4) the number of stars in the galaxy is about 160 million tons = 1.6 * 10 ^
