A toy top has a mass of 32.0 g Cu. How many atoms Cu are in this spinning top, given that the average atomic mass of copper is 63.55 g/mol Cu ?

A compound contains only Mn and F. The ratio of Mn and F is 2.54 moles of F per 1 mole of Mn. If the empirical formula is expressed at Mnfx, what is the numerial value of x?

This is not correct, if you don't use sig figs until the end and get 1.89882 = 1.898 it is NOT correct, how do I do this problem, because this isn't correct.

Give mw the answers only please be specific on what the answer is for both not just a bunch of calculations

I have calculated this problem various times, but every time I input the answer into the assignment it says it's wrong, I can't find the issue. What could it be?

Each sketch below shows three objects with an electric charge. In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on. ola -2 +3 -2 -2 I Don't Know Submit 2022 McGraw Hill LLC.

SC Score: 0 of 1 point Incorrect Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. Steam reforming of methane (CH4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. An industrial chemist studying this reaction fills a 75.0 L tank with 14. mol of methane gas and 5.8 mol of water vapor, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 2.3 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits.
