Explanation:
Something travelling at one foot per second is traveling about 0.682 miles per hour, so it should be roughly 60mph
The empirical formula is CrCl₃.
Explanation:
To find the empirical formula we use the following algorithm.
We divide each percentage by the atomic weight of each element:
for Cr 32.8 / 52 = 0.63
for Cl 67.2 / 35.5 = 1.89
The result will be divined by the smallest number:
for Cr 0.63 / 0.63 = 1
for Cl 1.89 / 0.63 = 3
The empirical formula is CrCl₃.
