Answer:
978.19° C
Explanation:
P1V1/T1 =P2V2/T2 Since the pressure is constant, this can be written as
V1/T1 = V2/T2 RE-ARRANGE TO
V2 * T1/V1 = T2 Note: T must be in Kelvin!!
1.5 L * (273.15 + 23) / (.355 L ) = T2 = 1251.338 K =978.19 C
The equation that we will use to solve this question is:
M1*V1 = M2*V2
where:
M1 is the initial concentration = 9.13*10^-2 M
V1 is the initial volume = 80 ml
M2 is the final concentration = 1.6*10^-2 M
V2 in the final volume that we need to find
Substitute with the values given in the equation to calculate the final volume as follows:
(9.13*10^-2*80) = (1.6*10^-2) * V2
V2 = 456.5 ml
Answer:
True
Explanation:
The oil drop experiment was carried out by Robert Millikan and Harvey Fletcher in 1909 to determine the charge of an electron. By balancing downward gravitation force with upward drag and electric force, they suspended small charged droplets of oil between two metal electrodes.
The charge over an oil droplet was often an integral value of e, was determined by changing the intensity of the electric field.
So, the given statement is true
