How do you find the atomic mass of Germanium?
Calculate the atomic mass of germanium. 1) First you would take the different percent’s of Germanium and multiple that with the different isotopes then divide it all by 100. therefore the atomic mass of germanium is 72.71 amu.
What is the atomic mass of Germanium 70?
69.924
How is atomic weight calculated?
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.
What is the mass number of Germanium 72?
71.9220758

What is the weight of arsenic?
74.9216 u
How do you extract arsenic?
Arsenic was extracted most efficiently by 5% H3PO4 with a maximum of more than 99% from the model soil. Sulfuric acid also showed high percentage extraction efficiency. On the other hand, C2H4O2 and oxidizing acids such as HNO3 and HClO4 showed low efficiency of As extraction compared with C6H8O7.
What is arsenic oxidation number?
The oxidation state of arsenic should, therefore, be either +3 or −3 depending on the relative electronegativity values of arsenic and the elements with which it is combined.
Which extraction method is used for arsenic detection?
Hydrochloric acid extraction
How is arsenic extracted from rice?
Cooking rice by repeatedly flushing it through with fresh hot water can remove much of the grain’s stored arsenic, researchers have found—a tip that could lessen levels of the toxic substance in one of the world’s most popular foods.
What brand of rice is lowest in arsenic?
Which Rice Has The Least Arsenic? Basmati rice from California, India, or Pakistan is the best choice, according to Consumer Reports data. These types of rice have about one third of the inorganic arsenic compared to brown rice from other regions.
