Solubility is the amount of solute that can dissolve in a given solvent at a specified temperature or pressure. Therefore, solubility is affected by pressure and temperature such that increase in temperature increases the rate of solubility of substances. In additional solubility depends on the molecular size of the solute such that when other factors are kept constant then a solute with small particles will dissolve more faster. Therefore, to increase the rate of solubility Ryan may; increase  the temperature of water.

A metal forms the fluoride MF3. Electrolysis of the molten fluoride by a current of 3.86 A for 16.2 minutes deposits 1.25 g of t
larisa86 [58]

<u>Answer: </u>The molar mass of the metal is 96.45 g/mol

<u>Explanation:</u>

The fluoride of the metal formed is MF_3

The oxidation half-reaction follows:

M\rightarrow M^{3+}+3e^-

Calculating the theoretical mass deposited by using Faraday's law, which is:

m=\frac{M\times I\times t(s)}{n\times F}       ......(1)

where,

m = actual mass deposited = 1.25 g

M = molar mass of metal = ?

I = average current = 3.86 A

t = time period in seconds = 16.2 min = 972 s            (Conversion factor: 1 min = 60 sec)

n = number of electrons exchanged = 3mol^{-1}

F = Faraday's constant = 96500 C

Putting values in equation 1, we get:

1.25g=\frac{M\times 3.86A\times 972s}{3mol^{-1}\times 96500 C}\\\\M=\frac{1.25g\times 3mol^{-1}\times 96500 C}{3.86A\times 972s}\\\\M=96.45g/mol

Hence, the molar mass of the metal is 96.45 g/mol

You bought a new car and estimated that your monthly payment would be $312. However, your actual payment amount was $325. How mu
Romashka-Z-Leto [24]

Answer:

The error would be $13.

Explanation:

Given data:

Actual payment = $325

estimated payment = $312

Error = ?

Solution:

Error =  Estimated payment - Actual payment

Error = $312  -  $325

Error = -$13

we can discard the negative sign and consider the absolute value. The error would be $13.
