Problem- A student didn't equalize the water levels inside the eudiometer tube with that of his water bath. The water level inside the tube was 10 cm higher than the water level outside the tube. He ignored the difference and proceeded with his calculations. What effect will this error have on his calculated atomic mass? Explain your rational.
