Can anyone help me with this question please? . Calculate the electromotive force (EMF) of the galvanic cell consisting of two zinc electrodes immersed in ZnSO4 solutions with different concentrations at T = 298 K: Zn | ZnSO4 (0.01 mol/l) || ZnSO4 (0.1 mol/l) | Zn.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

there are two significant figures.

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
