Answer:
Stanley Miller and Harold Urey
Explanation:
Experiments in which electricity was discharged into a vessel containing hydrogen gas, water vapor, methane, and ammonia were conducted by Miller and Urey.
Biochemists Stanley Miller and Harold Urey conducted an experiment in the 1950s which revealed many organic compounds can be spontaneously formed by simulating the early atmosphere conditions of Earth.
2 liter
Because the volume is 2 liter and the pressure and temperature are constant so nothing is happening.
So, we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles. molecules in a drop of water = 1.67 x 1021 water molecules.
