Two porous containers are filled with hydrogen and neon respectively. Under identical conditions, 2/3 of the hydrogen escape in 6 hours. How long will it take for half of the neon to escape? (This is a Graham's Law question)

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
