a word problem tells you that you have 27.8 moles of carbon dioxide. it asks how much that is in grams of carbon dioxide. luckily, they also supply a conversion factor. 1 mole of carbon dioxide is equal to 44 grams of carbon dioxide. you set up a conversion equation in the format shown in the image. what would you write in the space labeled 'a' in the diagram.
a. 27.8 moles of carbon dioxide
b. 1 mole of carbon dioxide
c. 44 grams of carbon dioxide

This question is about electrolysis. metal spoons can be coated with silver. this is called electroplating. suggest one reason why spoons are electroplated?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
