A gas diffuses 1/6 times faster than hydrogen gas (H2). What is the molar mass of the gas? (5 points)

a
59.95 g/mol

b
66.54 g/mol

c
68.68 g/mol

d
72.58 g/mol

Calculate the h3o+ concentration in a solution of acetic acid if the concentration of molecular acetic acid present at equilibrium is 9.97x10^-3 m and k for the dissociation is 1.86x10^-5. ch3cooh(aq)+h2o(> h3o^+(aq)+ch3coo^-(aq)

Iam in desperate need of with this !

Which compounds have the empirical formula ch2o? a.c2h4o2 b.c3h6o3 c.ch2o2 d.c5h10o5 e.c6h12o6
