Answer: The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.

AnswU GOT THIS!!!!!!!!!!!!!
Explanation:
Answer:200/3 M which is approximately equal to 66.6667 M
Explanation:Molarity is defined as the number of moles of solute per liter of solution.
It can be calculated as follows:

We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters
Substitute with the givens in the above equation to get the molarity as follows:
molarity =

Hope this helps :)
I took the test and the answer is chronium
Answer:
A. is alloyed with carbon and chromium to make stainless steel.
Explanation:
Steel is an alloy formed mainly of iron and carbon but some other metals like chromium are also added in little amounts.
Is steel, the percentage of iron and carbon together is about 90% and the rest metals fall in the 10% part.
Although the cost of steel is low, it has a very high tensile strength and that's why it is used in tools, ships, buildings, trains and in various types of infrastructures.
