Answer:
-6.51
Explanation:
Multiply 1.86 x 2 x 1.74 and then you get your answer.
The volume of gas that exerts a pressure of 457 mmhg if exerted a pressure of 2.50 atm when its volume was 25.0ml is calculated as follows
by use of Bolyes law formula that is P1V1=P2V2
P1= 457mmhg
V1=?
P1 = 2.50 atm = 2.50 x760 = 1900mmhg
V2= 25,0 ml
V1 from the formula above = P2V2/P1
= 1900mm hg x25 ml/ 457 mm hg = 104 ml
simple dimensional analysis:
8.2 grams * 1 mol / 22.99 grams * 6.02 x 10^23 atoms / mol = 2.1 x 10^23 atoms
Answer:
220
Explanation:
V₀= Vmax(D)/ (D) + km
0.66/100=vmax(130km)/(130km)+(km)
Vmax= 0.66×131/130×1000 =0.6650mm/d
kwat= vmax/ET
=0.665×10⁻³/ 3×10⁻⁶
= 0.22×10³
= 220
