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 man
Wewaii [24]
A.) The conversion factor is 1 amu = 1.66054 ^{-24}g

To know how many amu in 1.674x10^{-24}g grams of neutrons:
1.674x10^{-24}g ( \frac{x (amu) }{ 1.66054x10^{-24} g)}

=1.00811 amu

b.) The mass in grams of one lithium ion which has an atomic weight of 6.94 amu.

6.94 amu (\frac{6.66054 ^{-24} g}{1 amu}) = 4.62241x10 ^{23} g

c.) How many amu in 6.492x10^-23g potassium?

6.492x10^{-23}g ( \frac{x (amu) }{ 1.66054x10^{-24}g }) = 39.0957 amu
