Answer:
Wt Avg At Mass = 39.0229 amu
Explanation:
The Weight Average Atomic Mass in atomic mass units (amu) is the sum of the Weight Average Mass contributions of each isotopic mass. That is,
Wt. Avg. At. Mass (amu) = ∑ Wt. Avg. Contributions of each isotopic mass
Wt. Avg. Contribution = fractional abundance x isotopic mass(amu)
For this problem data:
Isotope %Abundance fractional Isotopic Wt Avg Isotopic
abundance mass(amu) Contribution (amu)
1 9.67% 0.0967 38 3.6746 amu
2 78.68% 0.7868 39 30.6852 amu
3 11.34% 0.1134 40 4.5360 amu
4 0.31% 0.0031 41 0.1271 amu
________________________________________________________
Wt. Avg. Atomic Mass (amu) = ∑ Wt. Avg. Contributions = 39.0229 amu
The answer is liter hope this helped :)
To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles

Answer: weathering due to freezing and thawing
Explanation:
The reason that caused these cracks to form is weathering due to freezing and thawing.
Weathering simply means the breaking down of rocks. In this situation, the boulder is freezed and thawed and due to this, as time progresses, it'll gradually be broken down. This is the reason why Mike saw the cracks even though there were no cracks the last time he went hiking.
