Solve first for the number of moles of sodium given that the mass is 2500 g by dividing the given mass by the molar mass of sodium.
moles sodium = 2500 g / 23 g/mol
moles sodium = 108.7 moles
Since in every mole of NaCl, there is only one mole of sodium then, we conclude that there are also 108.7 moles of NaCl. Multiplying the number of moles to the molar mass of sodium chloride (58.44), the answer would be 6,352.17 grams.
<em>Answer:</em>
- All of these answer are used in models.
<em>Explanation:</em>
The use of models is fundamentals tool in science. Scientists used the models to observe phenomena which happen too slowly, or happen too quickly or may to large or small process and how to extent it may dangerous for firsthand. They used different model depending upon whether which type of question is investigating.
A. The dark Bacteria showed resistance to the drug.
