The question is incomplete, the complete question is:
A chemist measures the amount of iodine solid produced during an experiment. He finds that 8.31 g of iodine solid is produced. Calculate the number of moles of iodine solid produced. Round your answer to the correct number of significant digits.
<u>Answer: </u>The number of moles of solid iodine produced is 0.0327 moles
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of solid iodine = 8.31 g
Molar mass of solid iodine = 253.8089 g/mol
Plugging values in equation 1:
Hence, the number of moles of solid iodine produced is 0.0327 moles
Answer:
1.67×10^-1
Explanation:
Use the formula n=m/R.M.M
Find the R.M.M. Formula of the compound is AgNO3.
So Ag mass is 108, N mass is 14, and O mass is 16.
So 108+14+(16×3)=170.
Than use formula n=28.39/170 giving 0.167. In scientific notation 1.67×10^-1.
