The formula for CGR is (Mass 2 - Mass 1)/(time 2 - time 1) * (1/Sampling Area). I sampled a crop at 30 days after planting and 50 days after planting on a 2 m² area of my research plot. The mass on day 30 was 300 g, and the mass on day 50 was 700 g. What is the CGR, in units of g/m²/day? Only put the number, not the units, in the answer.
