Answer:
220.42098 amu
Explanation:
(220 .9 X .7422) + (220 X .0.1278) + (218.1 X 0.13) = 220.42098 amu
These are weighted averages.
So, we will take mass of one and multiply by abundance percentage that is provided and add them together.
In order to calculate the average atomic mass, we have to convert the percentages of abundance to decimals. So, you get
(220 .9 X .7422) + (220 X .0.1278) + (218.1 X 0.13) = 220.42098 amu
I can’t see the picture but a atom I think
Answer:
1.05 x 10^-6
Explanation:
Lambda = c / f
f if frequency
c is intensity of light
lambda = 3 x 10^8 / 2.85 x 10^14
= 1.05 x 10 ^-6
