To calculate the flow rate of 2 L 05 NS (M) to infuse in 20 hr with a drop factor of 16 gtt/mL, we need to follow a few steps. Here's how to calculate the flow rate in gtt/min:First, we need to convert 2 L 05 NS to mL. 1 L = 1000 mL, so 2 L = 2000 mL. Since we have 50 mL left, we can add it up to get a total volume of 2050 mL.
Next, we need to calculate the total time in minutes, since the flow rate is in gtt/min. 20 hours = 20 × 60 = 1200 minutes.The formula for calculating the flow rate is: Flow rate (gtt/min) = Volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL)Now we can substitute the given values into the formula:
Flow rate (gtt/min) = 2050 mL ÷ 1200 min ÷ 16 gtt/mLFlow rate (gtt/min) = 0.10677 ≈ 0.11 gtt/min (rounded to 2 decimal places)Therefore, the flow rate of 2 L 05 NS (M) to infuse in 20 hr with a drop factor of 16 gtt/mL is approximately 0.11 gtt/min.

What is the wavelength of the light emitted by atomic Hydrogen according to Balmer's formula with m = 3 and n = 8? A) 389nm B)955nm C)384nm D)1950
The wavelength of the light emitted by atomic hydrogen, according to Balmer's formula with m = 3 and n = 8, is approximately 384 nm. So, the correct option is C.
According to Balmer's formula, the wavelength of the light emitted by atomic hydrogen can be calculated using the equation:
1/λ = R(1/m² - 1/n²)
Where λ is the wavelength, R is the Rydberg constant (approximately 1.097 x 10^7 m⁻¹), m is the initial energy level, and n is the final energy level.
In this case, m = 3 and n = 8. Plugging these values into the formula, we have:
1/λ = R(1/3² - 1/8²)
1/λ = R(1/9 - 1/64)
1/λ = R(55/576)
λ = 576/55 * 1/R
Substituting the value of the Rydberg constant, we get:
λ = 576/55 * 1/(1.097 x 10^7)
λ ≈ 3.839 x 10⁻⁷ meters
λ ≈ 384 nm
Therefore, the answer is option C) 384nm.

If an object weighs 3.4526 g and has a volume of 23.12 mL, what is its density?
Select one:
a. 0.15 g/mL
b. 0.149 g/mL
c. 1.50 x 10^-1 g/mL
d. 0.1493 g/mL
If an object weighs 3.4526 g and has a volume of 23.12 mL, the density of the object will be 0.1493 g/mL.
Density calculationTo calculate the density of an object, you need to divide its mass by its volume. In this case, the mass of the object is 3.4526 g and its volume is 23.12 mL.
Density = Mass / Volume
Density = 3.4526 g / 23.12 mL
Calculating the density:
Density ≈ 0.1493 g/mL
In other words, the density of the object is 0.1493 g/mL.

How much is 1 ug.min/ml in 1 mg.h/L?
ug/min/ml stands for micrgram per min per millilitre.ug/min/ml is generally used in the field of pharmacokinetics.To generally measure the mean concentration of any drug. These parametres are highly quantitative thus the chances of error is really high.
The units in which pharmacokinetic concepts are represented are a characteristic of the words' definitions and have an impact on the results of numerical calculations.
Consistency in symbol usage would minimise errors that might occur when interpreting values presented for different terms. The specific meaning of a phrase or concept as defined can frequently be clarified by carefully considering the units associated with it.To convert 1 ug/min/ml to mg/h L, the following is the calculation:1 ug/min/ml = 60 ug/h/L1 ug/min/ml = 0.00006 mg/h/L.Thus, 1 ug/min/ml is equal to 0.00006 mg/h/L.
Therefore, the answer is 0.00006.

pick the name for the given organic molecule: group of answer choices 2-ethylpentane 2-methylpentane 4-methylpentane 2-hexane
The given organic molecule has the molecular formula C7H16. Since there are no functional groups present in the molecule, it is an alkane.
The molecule has a chain of six carbon atoms and a branched chain containing two carbon atoms. The name of the molecule is derived from the longest carbon chain, which is six carbon atoms long, so the root name of the molecule is hexane. The two carbon atoms on the side chain are attached to the second carbon atom on the main chain, so it is called 2-ethylhexane the correct answer is 2-ethylhexane.
