We know that there is 1 mole of Mn for every 1 mole of
KMnO4, therefore the molarity of Mn is similar with KMnO4:
Mn = 0.00300 M
Molar mass of Mn is 54.94 g / mol. Molarity (M) is moles /
L, therefore:
Mn = (0.00300 moles / L) * (54.94 g / mol) * (1000 mg / g)
<span>Mn = 164.82 mg / L = 164.82 ppm</span>
About 255.3 grams is the answer I believe. I just had a school work packet and had that question on it, and that is the answer that I had put on it I believe.
Answer:
When the following equation is balanced, what is the coefficient for HCl? Mg(s) + HCl(aq) -> MgCl2(aq) + H2(g) . 2. What are the coefficients that will balance the skeleton equation below? AlCl3 + NaOH -> Al(OH)3 + NaCl.
Answer:
0.54 J/goC
Explanation:
Recall that we define the heat transferred as ;
H= mcθ
Where;
H= heat transferred = 112300J
m= mass of the metal= 240g or 0.24 Kg
c= specific heat capacity of the metal = the unknown
θ= change in temperature = (880°C-13°C) = 867°C
Substituting values and making the specific heat capacity the subject of the formula;
c= H/mθ
c= 112300/ 240×867
c= 0.54 J/goC
Hence, the specific heat capacity of the metal is 0.54 J/goC.
