Answer is: mass of insulin in the bottle is 8500 <span>milligrams</span> or 8.5 grams.

V(insulin) = 425 ml; volume of solution.
d(insulin) = 20.0 mg/ml; density of solution.
m(insulin) = V(insulin) · d(insulin).
m(insulin) = 425 ml · 20 mg/ml.
m(insulin) = 8500 mg.
m(insulin) = 8500 mg ÷ 1000 ml/l.
m(insulin) = 8.5 g.

Describe the smell of Na+ and H+
KIM [24]

Answer:

Sodium ion ( Na+) is known to have no smell at all but however appears salty which is the reason why the compound Sodium Chloride has the same type of taste.

Hydrogen ions ( H+) are known to have no taste which implies it being tasteless. It is also important to note that it has no smell too when perceived (odorless).

Which is the best reason for choosing the beaker for heating the solution? The beaker is the only container that can withstand h
lyudmila [28]

Answer: The beaker will not tip over when placed on the hot plate


Justification:


Since beakers have flat surface bottoms (usually and this is the condition to use them for this particular application) they can be placed safely on the hot plate without the risk that the they tip over.


Beakers are wide mouth cylindrical vessels used in laboratories to store, mix and heat liquids. Most are made of glass, in which case the glass is resistant to the flame and does not break when exposed to high temperatures or when is heated by direct contact on a hot plate.


So, their safe shape (flat bottom) that makes them stable, along with their ability to withstand high temperatures, make them suitable to heat solutions in laboratories.
