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?

Answer :

(a) The number of amu is 1.008 amu.

(b) The mass of one lithium atom is

(c) The number of amu is 39.09 amu.

Explanation :

As we are given that conversion factor:

(a) To calculate the number of amu.

As, of neutrons = 1 amu

So, of neutrons =

Thus, the number of amu is 1.008 amu.

(b) To calculate the mass of one lithium atom.

As, 1 amu of lithium atom =

So, 6.94 amu of lithium atom =

Thus, the mass of one lithium atom is

(c) To calculate the number of amu.

As, of neutrons = 1 amu

So, of neutrons =

Thus, the number of amu is 39.09 amu.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
