A Ringer’s solution contains the following concentrations of cations: 149 mEq/L of Na+, 4 mEq/L of K+, and 5 mEq/L of Ca2+. If Cl− is the only anion in the solution, what is the Cl− concentration in milliequivalents per liter?
Express the concentration in milliequivalents per liter to three significant figures.
c=?mEq/L

the answer is c

tell me if wrong

c. orbital shape i hope this is correct

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
