Answer:
The answer to your question is: 85.458 amu
Explanation:
data
Rubidium-85 A = 84.9118 amu abundance = 72.15%
Rubidium - 87 A = 86.9092 amu abundance = 27.85%
Atomic weight = ?
Atomic weight = 84.9118(0.7215) + 86.9092(0.2785)
Atomic weight = 61.2538 + 24.2042
Atomic weight = 85.458 amu
Answer:
Explanation:
Hello,
Percent composition is defined as:
%
Whereas is the subscript in the formula, the atomic mass of the ith element and the compound's molecular mass, thus, solving for :
Now, divining each over the least one () we get:
Finally the empirical formula turns out into:
Best regards.
Answer:
mass
Explanation:
How much does air weigh? It might not seem like it, but air has weight. Anything with mass has weight, and we know air has mass because (for example) we can feel it when the wind blows. The total weight of the atmosphere exerts a pressure of about 14.7 pounds per square inch at sea level.
