Your advisor has given you a tube of GMP that has been sitting in the freezer for many years and wants to know the concentration. There is one problem: the spectrophotometer in the lab has been 'optimized' for use with proteins and only measures at 280 nm. You decide to give it a try. After getting and absorbance reading of 0.2, what is the concentration of GMP in the tube (assuming a 1 cm path length).

2.22 × 10^-5M

Explanation:

From Beer-Lambert's law;

A=εcl

Where A = absorbance of GMP= 0.2

ε= molar extinction coefficient of GMP = 9000 M-1cm-1

c= concentration of GMP= the unknown

l= path length = 1 cm

c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm

c= 2.22 × 10^-5M

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
