How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
