We know that the density of gold = m/v
the volume is given in cm, so you have to convert each value into meters so you have .6m X .25m X .15m the density of gold is 19.3 x103 KG mass = density X volume mass = 19.3 x 103(.6 x .25 x .15) mass = 434.25 kg
A solution is a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another substance (solvent). When a liquid is fully saturated with dissolved solid, it means that no more solute can dissolve in the solution at that temperature, and the solution is said to be saturated.
You can find the refractive index of a solution using a refractometer, which measures how light bends as it passes through the solution. The refractive index is calculated by comparing the speed of light in a vacuum to the speed of light in the solution. The refractometer provides a numerical value that corresponds to the refractive index of the solution.
A spectrophotometer is typically used to measure the wavelengths of light absorbed by a solution. This instrument can determine the amount of light of a specific wavelength that is absorbed by the solution, which can provide information about the composition of the solution.
A solution can exist as a solid, liquid, or gas. Examples include alloys (solid solutions), soda (liquid solution), and air (gas solution). Solutions are defined as homogenous mixtures of two or more substances.
Photons absorbed by a solution "disappear" and the energy they brought with them is transferred into the solution. That energy appears in the "activity" of the atoms, molecules and/or ions in the solution. The kinetic energy of these particles will increase because of the added energy.
To effectively clean a moldy backpack, start by removing any visible mold with a brush or cloth. Then, mix a solution of water and mild detergent and scrub the affected areas. Rinse the backpack thoroughly and let it dry completely in a well-ventilated area. Consider using a mold-killing solution or vinegar for stubborn mold stains.

The solution to an inequality generally is a region with one more dimension. If the inequality/equation is of the form x < a or x = a then the solution to the inequality is the 1 dimensional line segment while the solution to the equality is a point which has no dimensions. If the inequality/equation is in 2 dimensions, the solution to the inequality is an area whereas the solution to the equality is a 1-d line or curve. And so on, in higher dimensional spaces.
To clean your canvas backpack with faux leather trim, start by emptying the bag and shaking out any debris. Use a soft brush or cloth to remove surface dirt, then mix a solution of mild detergent with warm water. Dampen a cloth with the solution, gently scrub the canvas, and wipe the faux leather with a separate damp cloth. Finally, allow the backpack to air dry completely before using it again.
Parallel but non-coincident or, in more than 2 dimensions, they are skew.
A solution has only one phase.A suspension has two phases.A colloid has two phases but the colloidal particles have dimensions under 1 micrometre.
A solution doesn't contain solids.A suspension contain insoluble solids.A coloid has insoluble particles with the dimensions between 1 nm and 1000 nm.
A solution has only one phase.A suspension has two phases.A colloid has two phases but the colloidal particles have dimensions under 1 micrometre.
Colloids are classified frequently as solutions because the particles have very small dimensions.
Let the number of unknowns be N. The solution space may have N, N-1, ..., 0 dimensions or may not exist. If a solution exists and the dimension of the solution space is 0, then there is exactly one solution,. If the dimension of the solution space > 0, then there are infinitely many solutions.
The colloid solution is very stable and the particles have dimensions between 1 and 1 000 nm.In a suspension particles are over 1 0000 nm and can be settled.
We identify a set of points in the relevant space which are part of the solution set of the equation or inequality. The space may have any number of dimensions, the solution set may be contiguous or in discrete "blobs".
