Answer 1
Answer:

Answer:

a. The concentration of β-galactosidase  

Explanation:

β-Galactosidase is an enzyme that hydrolyzes ß-D-galactosides like lactose to glucose and galactose.

It also cleaves o-nitrophenyl-β-D-galactoside (ONPG) to yield galactose and o-nitrophenol, which is yellow, and can be measured by its absorption at 420 nm.

If the concentration of ONPG is greater than that of β-galactosidase, the concentration of o-nitrophenol produced is proportional to the concentration of the enzyme.

Molar mass ammonia:

NH₃ = 17.031 g/mol

n = (m)/(M)

n = (1.2*10^3 g)/(17.031 g/mol)

n = 70.459 moles
