    Thank you so much! This was the most helpful interconverting number of atoms and mass of compound I've seen. None of the other ones had this problem. I love how you explained that we needed to go from Chem formula to Na to MM. It was helpful to see it laid out like that.

    i did the exact same way and got it wrong. It tells me the actual method was to divide the 1.0*10^9/6.022*10^23(avagadro's number). Then divide that number by the amount of hydrogen which is 10. Then multiply that number by the molar mass of B4H10 and thats the actual answer, which is pretty much the same as ur method??

    how did you get the -15?

    • @TheChemistryTutorChannel
      @TheChemistryTutorChannel  3 роки тому +1

      10^-15 is the power I get once the calculations are completed. One thing that makes unit conversions difficult for students is putting it into the calculator! Sometimes, order of operations can get mixed up and your answer will be different from the correct one. Try multiplying 1.0 x 10^9 by everything across the top first, then hit enter. Then, divide by everything in the denominator of each conversion factor and hit enter to get the final answer.

      @@Maria-jr4xy I got 8.8546*10^-15. I think you're probably not putting it into your calculator correctly. When you use numbers in scientific notation, you have to put them in parentheses, otherwise the calculator will fudge up the order of operations. It should look like this:
      (1*10^9)/10= 100,000,000
      100,000,000/(6.022*10^23)= 1.66057788*10^-16
      (1.66057788*10^-16)*53.323= 8.85469943*10^-15 (then round to the correct sig figs)
