What concentration of so32– is in equilibrium with ag2so3(s) and 2.60 × 10-3 m ag ? the ksp of ag2so3 can be found here?

1 answer:

8 0

When the Ksp of Ag2SO3 is 1.5 x 10^-14

and when the reaction equation is:

Ag2SO3 ↔ 2Ag+(aq) + SO3-- (aq)

so,

Ksp = [Ag+]^2 *[SO3--]

by substitution:

1.5 10^-14 = (2.6 x 10^-3)^2 *[SO3--]

∴ [SO3--] = 2.2 x10^-9

If an object has a density of 0.55 g/mL, what is its density in cg/L?

expeople1 [14]

"cg" is centigram, which is one-hundredth of a gram.

I will first convert from g to cg (multiply by 100), then from mL to L (multiply by 1000).

$\frac{0.55g}{mL}*\frac{100cg}{1g}*\frac{1000mL}{1L}=55,000\frac{cg}{L} \ or \ 5.5e4\frac{cg}{L}$

An FM radio station broadcasts electromagnetic radiation at a frequency of 103.4 MHz (megahertz; MHz =106sâ€“1). Calculate the w

kap26 [50]

Answer:

$Wavelength=2.899\ m$

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength$

c is the speed of light having value $2.998\times 10^8\ m/s$

Given, Frequency = 103.4 MHz = $103.4\times 10^{6}\ Hz$ ( as 1 MHz = 10⁶ Hz)

Thus, Wavelength is:

$Wavelength=\frac{c}{Frequency}$

$Wavelength=\frac{2.998\times 10^8}{103.4\times 10^{6}}\ m$

$Wavelength=2.899\ m$
