It's a dimensional analysis problem but you don't have to solve it. I just need to know how many sig figs would the answer have. The numbers (with units) used are:
1 mol pennies
1 mol dollars per 100 mol pennies
6.02 x 10^23 dollars per 1 mol dollars
1 in oer 1,000,000 dollars
1 ft per 12 in
1 mile per 5280 ft
Now in chemistry class we learned that some measurements have infinity sig figs because they are an exact measurement, such as in 5280 ft is 1 mile, 5280 ft actually has infinity sig figs instead of 3 because in a mile there are actually 5280.00000000000000000000000000000000000000000000000..... feet. But I'm not good at determining what has infinity sig figs. How many sig figs will be in the final answer? You don't really need to see what the problem looks like to answer this, but the answer is 9.501262626 x 10^10 miles. Thank you so much for answering.
