Mathematical formula of Ideal Gas Law is PV=nRT
where: P-pressure,
V-volume
n-number of moles; m/MW
T-Temperature
m-mass
d-density ; m/V
MW-Molecular Weight
R- Ideal Gas constant. If the units of P,V,n & T are atm, L, mol & K respectively, the value of R is 0.0821 L x atm / K x mol
Substituting the definitions to the original Gas equation becomes:
d= P x MW / (RxT)
Solution : d= .90atm x 28 g/mol (CO) / 0.0821Lxatm / mol x K x 323 K
d = 25.2 g / 26000 mL
d = .0.00096 g/mL is the density of CO under the new conditions
Answer:
5496 g of epinephrine
Explanation:
From the question, 5.00 moles of epinephrine is required to make Epipen.
Molar Mass of epinephrine = 183.20 g/mol
mass of 5 moles of epinephrine=
Therefore, 30.00 moles of epinephrine needs 30.00 * 916/5 =5496 g of epinephrine
The answer is 0.0035
In order to figure out kg, you have to know that 1 milligram is equal to 1/100000 kilograms. You take the amount of mg's that you have, which is 3500, and divide it by 1000000 which will give you your answer.
3500/1000000= 0.0035 kg
Answer:
They occur between polar molecules.
Explanation:
- Dipole-dipole Forces act between polar molecules that is between molecules that possess dipole moments.
- It is electrical interactions between polar molecules.
- The larger the dipole moments, the greater the force.
- H-bonding is a special type of dipole-dipole forces that is between H-atom and an electronegative atom such as: N, O, F.
- Dipole-dipole Forces are stronger than London dispersion forces.
<em>So, the right choice is: They occur between polar molecules.</em>
Not completely sure but I’d say salt comes from small ocean orgasisms
