The problem above is simply a conversion problem. We only need a conversion factor to convert the units from amu to kg. From a conversion table, we will see that 1 amu is equal to 1.66x10^-27 kg. We convert as follows:

0.13261 amu ( <span>1.66 × 10^-27 kg / 1 amu ) = 2.20x10^-28 kg </span>

(58) The pressure of a gas in a tank is 422 psi at

wel

<h3>Answer:</h3>

1270 Psi

<h3>Explanation:</h3>

<u>We are given;</u>

Pressure in the tank, P₁ as 422 psi
Temperature in the tank, T₁ as 20.0 K
New temperature in the tank, T₂ as 60.0 K

We are required to determine the pressure at 60.0 K

We are going to use the pressure law;
According to the pressure law, the pressure of a gas is directly proportional to the temperature at constant volume.

That is; $P\alpha T$

Thus, $\frac{P}{T}=constant$

At different pressures and temperature;

$\frac{P1}{T1} =\frac{P2}{T2}$

Thus, rearranging the formula;

$P2=\frac{P1T2}{T1}$

Hence;

$P1=\frac{(422Psi)(60K)}{20}$

$P1=1266Psi$

Therefore;

P₂=1266 Psi

= 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

A neutral atom possesses an atomic number of 15 and an atomic mass of 31. Three electrons are gained. What is the result of this

Katyanochek1 [597]

<em>Answer:</em> an anion will form with -3 charge.

<em>Explanation;</em>

The atomic number of the given atom = 15

Atomic number = number of protons

The number of protons of the given atom = 15

The atomic mass of the given atom = 31

Atomic mass = number of protons + number of neutrons

Hence,

number of neutrons = atomic mass - number of protons

= 31 - 15

= 16

Since, the atomic number is 15, the given atom is P which has the atomic number as 15.

In the neutral compound,

number of protons = number of electrons

Hence,

the number of electrons of the neutral atom = 15

But, the atom has gained 3 electrons.

Gaining of electrons will form anions.

Hence, the atom will be converted into anion which has -3 charge on it.

But the atomic mass, atomic number, number of protons and number of electrons will not be changed
