Calculate the ratio of H+ ions to OH-ions at a pH = 7.
Find the concentration of Htions to OH-ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OH concentration. Record this
calculated ratio in Table A of your Student Guide.
Compare your approximated and calculated ratios of H+
ions to OH-ions at a pH = 7. Are they the same? Why or
why not? Record your comparison in Table A.
What is the concentration of H+ ions at a pH = 7?
mol/L
What is the concentration of OH-ions at a pH = 7?
mol/L
What is the ratio of Htions to OH-ions at a pH = 7?

you gotta add the following molecules so we can give u an answer

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
