Answer:
[Au] = 0.171 M
Explanation:
For this question, we assume the rock is 100 % gold.
First of all, we determine the moles of gold
67.3 g . 1mol/ 196.97g = 0.342 moles
Molar concentration is defined as the moles of solute, contained in 1L of solution.
Our solution volume is 2L.
M = 0.342 mol / 2L = 0.171
Molar concentration, also called molarity of solution is the most typical unit of concentration.
Answer:
False
Explanation:
Some substances don't have to be
Scoria
Explanation:
Scoria is a rock that is commonly made up of gas bubbles and minerals such as hornblende, muscovite, olivine, lucite and or plagioclase.
Scoria is an extrusive igneous rock with a lot of cavities and vesicles indicating gas bubbles.
- Scoria is product of basaltic magma.
- It has nearly the same composition as basalt since it originates from it.
- They silica deficient and very fine grained with holes in them.
- The holes shows channels by which trapped gases are forcefully ejected out.
- They are usually found associated with cindercone volcanoes.
