Assuming all other variables are constant, if the pressure of a gas is increased from 2. atm to 6 atm the volume would change from 6.0 liters

Iwll give extra points to who gets this for ! what type of reaction is this? ?

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
