Planet earth has a mass of 5.9726x10Ā²ā“ kg.then: 5.9726x10Ā²ā“ kg=100% of the total earth mass.if the waterĀ“s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10Ā²ā“ %*10ā»ā“ %x=(5.9726x10Ā²Ā³ kg)(5*10ā»ā“ %) / 100 %=2.9863x10Ā¹ā¹ kganswer: the mass of the planetĀ“s water would be 2.9863 x 10Ā¹ā¹ kg.
