m=12grams Molar Mass= 180.18 V=.1L n= m/MM= 0.067 moles. Molarity= n/V= .067/.1= .67 M1V1=M2V2 => 0.67(.05)=M2(.5) Solve for M2 and you get .067 M= m/VMM : Molarty= mass/ Volume x Molar Mass so m= MVMM : mass= Molarity x Volume x Molar Mass m= .067(.1)(180.18)= 1.21 Just ...

Hello all, In our math class, we are practicing the trigonometric identities (i.e., sin^2(x)+cos^2(x)=1 or cot(x)=cos(x)/sin(x). Now, we are working on proofs that two sides of an equation are equal (for example, sin(x)*csc(x)=1; sin(x)csc(x)=sin(x)/sin(x)=1; 1=1). I am not ...
