Explanation:
The answer is A: Between 50 and 5,000 amino acids
Answer:
5.6 * 10^3
this is because when thinking about scientific notation you know that you have to include a decimial and how many times you are moving it and whether it is a negative of a positive.
this means that you would take 5600 and you would put the decimal inbetween 5 and 6 because they are significant numbers and then you would have to figure out how many places to the right you need to go inorder to make it 5600
meaning you have to move it three times therefore it becomes
5.6 * 10^3
Answer:
You forget to compute the calculation systematically.
101.325 J/L*atm is obtained by dividing R in J/(mol*K) with R in L*atm/(mol*K)
Explanation:
Fo the given equation
Wrev = -nRtln(vf/vi)
We have the calculation below:
Wrev = -(1.000 mol)(0.08205 L*atm/mol*K)(298K)ln(10L/1L)
Wrev = -24.4509*ln(10) = -24.4509*2.303 = -56.3 L*atm
However, the unit was converted from L*atm to J by using a conversion unit derived from the ratio of gas constant (R) in J/(mol*K) and L*atm/(mol*K).
R = 0.082057 L*atm/(mol*K)
R = 8.3145 J/(mol*K)
Therefore, we can derive a conversion unit for L*atm to J as:
[8.3145 J/(mol*K)]/[0.082057 L*atm/(mol*K)] = 101.325 J/L*atm
Thus:
Wrev = -56.3 (L*atm) * 101.325 (J/L*atm) = -5705 J
Answer:
<u></u>
Explanation:
<u>1. Calculate the number of moles of NiCl₂</u>
a) Identify the known variables
- V =0.800 liters
- M = 0.531M
- n = ?
b) Formula
c) Clear n
<u>g) Substitute and compute</u>
<u>2. Convert moles to grams</u>
a) molar mass of NiCl₂
- 129g/mol (shown in the problem)
b) Unit canceling method
Use the factors in order to cancel the units to obtain grams
Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).
c) Round to 3 signficant figures
