Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 125 mL of insulin at a concentration of 50.0 mg/mL . What is the total mass of insulin in the bottle?

the total mass of insulin in the bottle would be 3.75 g

hope this helps :)

Explanation:

c= 50 mg/mL  

m = ?

v = 125 mL

c=m/v

=

m=30×125

m=3750 mg or 3.75 g

i don,t know so just answer mine

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
