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.

There are a few grammar errors in the text. Here is the corrected version:

"The data in each treatment suggests that at 1.5M H2SO4, there was an increased volume of hydrogen gas and an increased reaction rate to generate hydrogen gas, as indicated by the range of the average volume difference of 28mL compared to 0.1M H2SO4. This increase can be attributed to the higher availability of hydrogen ions in the solution. The overall graph shows a linear trend of positive correlation, supporting the hypothesis of an increase in the volume of H2 with increased concentration. However, the high concentrations observed also have a large percentage uncertainty, which may indicate low precision or variation in the data due to external factors."
