Answer:

P = 28.5 atm

Explanation:

PV = nRT => P = nRT/V

P = Pressure = ?

n = moles of sample = mass/molar mass = 26g/44g·mol⁻¹ = 0.619 mole CO₂

R = gas constant = 0.08206 L·atm/mol·K

T = temperature in Kelvin = (35 + 273)K = 308K

V = volume in Liters = 550 ml = 0.550 L

Pressure (P) = nRT/V

= (0.619 mole)(0.08206 L·atm/mol·K)(308K)/(0.550 L) = 28.5 atm

What volume of a 0.2089 M KI solution contains enough KI to react exactly with the Cu(NO3)2 in 40.88 mL of a 0.3842 M solution o

tatyana61 [14]

Explanation:

As molarity is the number of moles placed in a liter of solution. Therefore, no. of mole = Molarity × volume of solution in liter

Hence, moles of $Cu(NO_{3})_{2}$ will be calculated as follows.

No. of mole of $Cu(NO_{3})_{2}$ = $0.3842 M \times 0.04388 L$ = 0.0168 mole

According to the given reaction, 2 mole of $Cu(NO_{3})_{2}$ react with 4 mole of KI.

Therefore, for 0.0168 mole amount of $Cu(NO_{3})_{2}$ required will be as follows.

$Cu(NO_{3})_{2}$ = $0.0168 \times \frac{4}{2}$

= 0.0337 mole of KI

Hence, volume of KI required will be calculated as follows.

Volume = $\frac{\text{no. of moles}}{Molarity}$

Volume of KI = $\frac{0.0337}{0.2089}$

= 0.1614 liter

= 161.4 ml (as 1 L = 1000 mL)

Thus, we can conclude that 161.4 ml volume of a 0.2089 M KI is required for the given situation.

The molecular mass of octane is 114.22 g/mol. What is the mass of 22.05 mol of octane?

strojnjashka [21]

<span>In this item, we are asked to calculate for the mass of 22.05 mole of octane given that its molecular mass is equal to 114.22 g/mol. To answer this item, we simply have to multiply the number of moles with the molecular mass. That is, (114.22 g/mol)(22.05 mol) which is equal to 2518.221 grams. </span>
