is there any grammar errors
The data in each treatment suggest that at 1.5M H2SO4, there was increased volume of hydrogen gas and increased reaction rate to generate hydrogen gas as the range of the average volume difference of 28mL compared to 0.1M H2SO4 as more hydrogen ions available in the solution. The overall graph shows linear trend of positive correlation fitting the hypothesis of increasement of volume of H2 with increased concentration. However, the large percentage uncertainty observed in high concentrations may indicate that there is low precision or variation in the data caused by external factors.
