Use the conversion factor 1amu=6.66054 x 10^24 to answer the following questions.
a) 1.674 x 10^24 g of neutrons is how many amu?
b)what is the mass in grams of one lithium atom(lithium has an atomic weight of 6.94 amu)
c)6.492 x 10^23 g of potassium is how many amu?

Best ResponseYou've already chosen the best response.1a)You mean\[1\text{amu}=1.66054\times10^{24}\text g\]so the conversion from grams to amu will be\[1.674\times10^{24}\text g(\frac{1\text{amu}}{1.66054\times10^{24}\text g})\]

Best ResponseYou've already chosen the best response.0can you help me with this one also please. Complete combustion of 8.00g of a hydrocarbon produced 25.6g of CO2 and 9.15g of H2O. What is the empirical formula of the hydrocarbon? I have to leave. I will be back. Thanks for A.

Best ResponseYou've already chosen the best response.1b)\[\frac{6.94\text{amu}}{1\text{Li atom}}\cdot\frac{1.66054\times10^{24}\text{g}}{1\text{amu}}\]check the units to see that this gives g/Li atom

Best ResponseYou've already chosen the best response.1c)\[?\text g\times\frac{?\text{amu}}{?\text{g}}=?\text{amu}\]you should be able to figure out the numbers yourself after the last two problems
