Alisiya [41]3 years ago
6 0


6,50g of ZnSO4 is 0,04 moles


Mass of ZnSO4  :    

m=6,50g

<span>Molar mass of ZnSO<span>4 :     </span></span>

M=M(Zn)+M(S)+4*M(O)

M=65,38 g/mol+32,06 g/mol+4*15,99 g/mol

M=161,40 g/mol

Molarity of ZnSO4 :

n=m/M          

n=6,50g/161,40g/mol

n=0,04 mol

What results when two waves that are completely out of phase meet?
ELEN [110]

Answer:

The result is a superposition which is twice the amplitude of each input wave. Φ = π means the two waves are completely OUT OF PHASE, and so add completely destructively. The result is a superposition which has no amplitude at all.

A chemist prepares a solution of sodium thiosulfate by measuring out of sodium thiosulfate into a volumetric flask and filling t
marshall27 [118]

Mass of sodium thiosulfate Na_{2}S_{2}O_{3} is 110. g

Volume of the solution is 350. mL

Calculating the moles of sodium thiosulfate:

110. g Na_{2}S_{2}O_{3} * \frac{1 mol Na_{2}S_{2}O_{3}}{158.1 g Na_{2}S_{2}O_{3}} = 0.696 molNa_{2}S_{2}O_{3}

Converting the volume of solution to L:

350. mL * \frac{1 L}{1000 mL} = 0.350 L

Finding out the concentration of solution in molarity:

\frac{0.696 mol}{0.350 L} =  1.99 mol/L
