To convert a number without the use of the expression 10^-4 you would have to treat it like an integer line for instance on an integer line the negative is to the left and the positive number is to the right so 3.91*10^-4 means that the decimal would have to move 4 places to the left so the answer would be .000391 instead of 3.91*10^-4.
I hope this helps you :)
The average atomic mass of the element is the weighted average atomic mass of element with respect to the natural abundance of all the isotopes.
isotopes are atoms of the same elements with different mass numbers , in other words same number of protons but different numbers of neutrons.
to find the average atomic mass we need to know the atomic masses of all the isotopes in addition to the natural abundance percentages of the isotopes.
answer is we need to know the atomic masses of the isotopes as well
Is this multi choice or no?
Determine the mass of each of the following amounts. a. 1.366 mol of
NH3
, b. 0.120 mol of glucose,
C6H12O6
, c. 6.94 mol barium chloride,
BaCl2
, d. 0.005 mol of propane,
C3H8
