Physical properties of objects section 3 the conversion of some units in the density of matter, such as the conversion of units between ml and M3, please be more detailed, and the following questions! What is the mass of 1.100ml gasoline? What is the volume of 1.29Kg air? 2. A 2.5-liter bottle is filled with blended oil. The mass of the oil is 2kg, so what is the density of the oil? 3. It is necessary to select excellent grain seeds for agricultural scientific experiments. In an experiment of selecting wheat seeds, we need to measure the approximate grain number of 1kg wheat seeds and the approximate mass of a grain of wheat seeds. We only have a 200g pallet balance on hand. How can we complete the measurement quickly?

1 ml (1ml) = 1 cubic centimeter 1 liter (L) = 1 cubic decimeter 1 cubic meter 1 cubic meter = 1000 cubic decimeter (L) = 1000000 cubic centimeter (ML) gasoline mass m = gasoline density x gasoline volume gasoline density can be found in the density table. It should be noted that gasoline volume must be converted to square meter, that is 100 / 1000000 cubic meter empty
