No of moles= 88/44 =2
therefore no. of molecules =
therefore no.of molecules= 12.046*10^23
The correct chemical formulae is CsBr
Hi,
Gases are most soluble in water under high pressure and low pressure.
Answer is D
Balance the equation
Answer:
The answer is (H30+) =3,55e-8M and (OH-)=2,82e-7M
Explanation:
We use the formulas:
pH= - log(H30+) and Kwater=(H30+)x(OH-)
pH= - log(H30+) ----< (H30+)= antilog- pH=antilog- 7,45=3,55E-8M
Kwater=(H30+)x(OH-)
(OH-)=Kwater/(H30+)= 1,00e-14/3,55e-8 = 2,82e-7
