Answer:
Explanation:
(1) first part of solution: we know stress= Force/Area ; Force= 400lb and Area as given
(2) Second part of the solution its the standard formula for Hoop stress and the formula explains all the terms
(3) Third part of the solution we know Strain= (Change in length)/original length and also the strain are substituted in terms of strain and youngs modulus
Further explanation are given in the attach document.
Answer: The molecular formula will be
Explanation:
If percentage are given and we are given total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 31.17 g
Mass of H = 6.54 g
Mass of O = 62.29 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of H=
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C=
For H =
For O =
The ratio of C: H: O= 1: 2.5: 1.5
Converting them into whole number ratios by multiplying by 2.
Hence the empirical formula is
The empirical weight of = 2(12)+5(1)+3(16)= 77 amu
The molecular weight = 231.2 amu
Now we have to calculate the molecular formula.
The molecular formula will be=
The molecular formula will be
The answer is B. because it starts at Conifer Seeds and ends at Northern goshawks.
