mv^2 =2* e*40k J/Cv=  sqrt(2* e*40k/m)
mv^2/r = F centripetal = evB2* e*40k/(210*sqrt(2* e*40k/m)*e) =BB=√e∗80,000∗m−−−−−−−−−−−/210

<span>Proteins that minimize fluctuations in pH are known as buffers. A buffering agent can be either a weak acid or weak base. Buffering agents are usually added to water to form a buffer solution, which only slightly changes its pH in response to other acids and bases being combined with it, particularly a strong acid or a strong base.</span>
        
             
        
        
        
Answer:


→ Molar Mas = <u>5</u><u>5</u><u>.</u><u>8</u><u>5</u><u> </u><u>g/</u><u>mol</u>

→ Molar Mass = <u>5</u><u>8</u><u>.</u><u>4</u><u>4</u><u> </u><u>g/</u><u>mol</u>

→ Molar Mass = <u>16.02 g/</u><u>mol</u>

→ Molar Mass = <u>7</u><u>4</u><u>.</u><u>1</u><u>0</u><u> </u><u>g/</u><u>mol</u>
