Answer:

V = 5.17L

Explanation:

Mass of gas = 8.7g

T = 23°C = (23 + 273.15)K = 296.15K

P = 1.15 atm

V = ?

R = 0.082atm.L / mol.K

From ideal gas equation

PV = nRT

P = pressure of the gas

V = volume of the gas

n = no. Of moles

R = ideal gas constant

T = temperature of the gas

no of moles = mass / molar mass

Molar mass of Chlorine = 35.5g / mol

No. Of moles = 8.7 / 35.5

No. Of moles = 0.245 moles

PV = nRT

V = nRT / P

V = (0.245 * 0.082 * 296.15) / 1.15

V = 5.9496 / 1.15

V = 5.17L

The volume of the gas is 5.17L

7.49 x 105 mm 34500 inches 0.45 miles 885 yards smallest to largest lengths

emmasim [6.3K]

30.962
34500
28512
31860

answer:

7.49 x 105 mm
0.45 miles
885 yards
34500 inches

reason:

I converted all the measurements to inches.
First, I multiplied 7.49x105 to get 786.45mm
Then, I divided it by 25.4 to get about 30.92 inches

Next, I converted 0.45 miles to inches by multiplying it by 63,360 to get 28,512 inches

For the yards, I took 885 and multiplied it by 36 to get 31,860 inches

Since the last one was already in inches, all I needed to do was put them in order from least to greatest

LuckyWell [14K]

Answer:

N-ethyl-2-methylpropan-2-amine

Explanation:

In this case, we have to start with the IR info. The signal on 3400 cm^-1 indicates the presence of a hydrogen bonded to the heteroatom. In this case, we have nitrogen in the formula, so we will have the amine group.

On the other hand, we have to analyze the NMR info:

a) We have 2 singlets => This indicates the presence of 2 different hydrogens without neighbors.

b) We have a triplet => This indicates the presence of CH3 bonded to a CH2.

c) We have a quartet => This indicates the presence of CH2 bonded to a CH3.

From b) and c) we can conclude that we have the ethyl group bonded to a nitrogen.

Finally, we have to add 4 more carbons in such a way that we only have a single signal. In this case the ter-butyl group.

In that way, we will have 2 singlets (from the CH3 groups in the ter-butyl and the H on the N). Also, we will have the quartet on the CH2 in the ethyl group and the triplet on the CH3 in the ethyl group
