Molarity of a solution = (number mol of solute)/ (volume of the solution)
1) Molar mass NaOH= M(Na)+M(O)+M(h)= 23.0+16.0+1.0=40.0 g/mol
2) 11.5 g NaOH *(1mol Naoh/40.0 g NaOH)=0.288 mol NaOH
3)Molarity (NaOH solution) =(0.288 mol)/(1.5 L)=0.192 M≈0.19 M
An inorganic compound is a substance that does not contain both carbon andhydrogen. A great many inorganic compounds do contain hydrogen atoms, such as water (H2O) and thehydrochloric acid (HCl) produced by your stomach. In contrast, only a handful of inorganic compounds contain carbon atoms.
Answer:
True
Explanation:
Fossil age can determine organism changes related to the time scale. Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time.
fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. However, by itself a fossil has little meaning unless it is placed within some context. The age of the fossil must be determined so it can be compared to other fossil species from the same time period. Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.
