We would like to make a golden standard kilogram in the shape of circular cylinder. The density of gold is 19.32 g/cm3. a) Find the volume of the kilogram standard of gold in cubic meter. b) In order to minimize the effect of surface contamination, the height of this golden standard kilogram is equal to its diameter. Find the height of this golden standard kilogram in mm.

Explanation:

a)  Using the provided information about the density  of gold, the sample size, thickness, and the following  equations and comersion factors, find the area of   the gold leaf:

Gold

First, find the volume of the sample and then find the area of the sample.

b.  Using the provided information from part ), the radius of the cylinder, and the following equation for the volume of a cylinder, find the length of the fiber :

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
