Assuming this is a true or false question, the answer would be True
Answer
36.45 u; X = Cl
Explanation:
The atomic mass of X is the <em>weighted averag</em>e of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its percent of the total).
Set up a table for easy calculation
.
0.7577 × 34.969 u = 26.496 u
0.2423 × 36.965 u = <u> 8.9566 u
</u>
TOTAL = 36.45 u
X = Cl
Answer:
See attached image.
Explanation:
The explanations are on the attachment. The numerical results are below.
1. 63g/7cm^3 = 9 g/cm^3
2. The m or mm must be converted so that the units are the same. 1 m = 1000 mm. I'll convert the meters to mm: 0.080 m = 80 mm.
480 mm^2/80 mm = 6 mm
3. L times L makes no physical sense, unless this is a new Star Wars technique for making dark matter. Entertaining, but useless.
well if you round to the nearest cent the number 0.332 move the decimal down 2 time so it would be 33 it the the answer would be "a"
im sorry if im wrong im trying my best to answer correctly please don't report my answer cause brainly mighty remove my account again.xd
