Answer:
8.8 yards per second

50 - 20 = 30 yards
30 yards/3.4 seconds = 8.8235
Answer:To find S, the number of shared
electrons, recall that
S = N-A
Explanation:UwU
The concentration may be expressed as % m/m, this is the mass of ions in 100 mass units of solution, whose formula is:
% m/m = [mass of ions / mass of solution]*100
Then,
%m/m = [8.5*10^ -3 grams of calcium ions] / [490 grams of solution] * 100 =
% m/m = 1.74 * 10^ -5 %
Answer: 1.74 * 10 ^ -5 %
