Answer:

Sample C has the highest density

Explanation:

Step 1: data given

Sample A has a mass of 224.96 grams

Sample B has a mass of 0.55632 lbs = 252.3425 grams

Sample C has a mass of 0.30648 kg = 306.48 grams

The volume is for all the sample equal

Step 2: Calculate density

We suppose the volume is 1000 mL

Density = mass / volume

Density sample A = 224.96 grams / 1000 mL = 0.22496 g/mL

Density sample B = 252.3425 grams / 1000 mL = 0.2523425 g/mL

Density sample C = 306.48 grams / 1000 mL = 0.30648 g/mL

Sample C has the highest density

What mass of iron (III) nitrate will be in 129.8ml of a 0.3556 molar aq iron (III) nitrate solution?
Anvisha [2.4K]

<u>Answer:</u> The mass of iron (III) nitrate is 11.16 g/mol

<u>Explanation:</u>

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Molarity of solution = 0.3556 M

Molar mass of Iron (III) nitrate = 241.86 g/mol

Volume of solution = 129.8 mL

Putting values in above equation, we get:

0.3556M=\frac{\text{Mass of iron (III) nitrate}\times 1000}{241.86 g/mol\times 129.8}\\\\\text{Mass of iron (III) nitrate}=11.16g

Hence, the mass of iron (III) nitrate is 11.16 g/mol

Estimate the percent ionic character of the co bond. (note that the electronegativity of c is 2.5 and that of o is 3.5.)
deff fn [24]

From the calcuation, the percent ionic character of the bond is  70%

<h3>What is percent ionic character?</h3>

The term percent ionic character has to do with the degree of ionic bonding that is contained in a compound. It can be estimated from the electronegativity of each element.

We can use the formula; 100(1 - e^(-ΔEN² / 4))

EN = χB − χA * 100/1

EN = 3.5 - 1.5 = 1

100(1 - e^(-1)^2/4)

= 70%
