1 kg ---------- 1000 g
4.84 kg ------ ?
4.84 x 1000 / 1 => 4840 g
D = m / V
7.86 =4840 / V
V = 4840 / 7.86
V = 615.77 cm³
1 cm³ ------------ 0.01 dL
615.77 ----- ?
615.77 x 0.01 / 1
= 6.1577<span> dL</span>
Answer:
4.1 x 10^-4 mol/L
Explanation:
For the equation
FeF2(s) --> Fe2+(aq) + 2F- (aq)
We have that for every mole of FeF2 we have a mole of Fe2+ and 2 moles of F-
FeF2(s) --> Fe2+(aq) + 2F- (aq)
1 1 2
If we have 2.05 x 10^-4 moles of Fe2+
FeF2(s) --> Fe2+(aq) + 2F- (aq)
2.05 x 10^-4 2 x 2.05 x 10^-4
2 x 2.05 X 10^-4 = 5.1 x 10^-4 moles
So if in the solution is measured 2.05 x 10^-4 mol/L of [Fe2+] we have 5.1 x 10^-4 mol/L of [F-]

Answer: Hello,Mass ratio charge is.....................
Explanation: In mass spectroscopy, the mass-to-charge ratio (symbols: m/z, m/e) of a cation is equal to the mass of the cation divided by its charge. ... The mass of the molecular ion is equal to the molecular weight of the compound. Thus, the mass-to-charge ratio of the molecular ion is equal to the molecular weight of the compound.
