4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
vovangra [49]

Answer:

0.36g

Explanation:

Given parameters and conversion to standard unit

 To solve this problem we must assume ideality

Volume of N₂H₄  =  350mL  = 0.35dm³

Temperature of container  = 50°C  = 50 + 273  = 323K

Pressure  = 885torr;

               760torr  = 1atm

               885torr  = \frac{760}{885}   = 0.86atm

Unknown:

Mass of the compound  = ?

Solution:

The mass of the compound can be derived using the expression below;

         Mass = number of moles x molar mass

molar mass of N₂H₄ = 2(14) + 4(1)  = 32g/mol

To find the number of moles;

       PV  = nRT

          n  = \frac{PV}{RT}

P is the pressure

V is the volume

R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

         n  = \frac{0.86 x 0.35}{0.082 x 323}   = 0.01mole

So,

    Mass  = 0.01 x 32  = 0.36g

Botox injections have been approved by the food and drug administration (fda) as a procedure to treat spasms of the flexor muscl
Nostrana [21]

Botox injections comprise Botulinum toxin and is used in the treatment of some kind of eye ailments, like strabismus (crossed eyes) and blepharospasm (involuntary blinking), to treat movement disorders (like torticollis, cervical dystonia) or muscle spasms/stiffness. It can also be used to minimize the cosmetic appearances of wrinkles.

However, due to certain side effects, the drug was ban by FDA, but it has been approved by the FDA for treating spasms of the flexor muscles. Although, there is a scenario that the claim for the application of the drug could be rejected in case of a lack of a medical necessity, that is if it does not fulfil the usual accepted professional medical standards of care.
