Answer:

$P_{tot}=465.27torr$

Explanation:

Hello there!

In this case, according to the given information, it will be possible for us to use the Dalton's law, in order to solve this problem. However, we first need to calculate the mole fraction of oxygen by firstly calculating the moles of each gas:

$n_{H_2}=\frac{14.0g}{2.02g/mol} =6.93mol\\\\n_{N_2}=\frac{84.0g}{28.02g/mol}=3.00mol\\\\n_{O_2}=\frac{64.0}{16.00g/mol} =2.00mol$

Next, we calculate such mole fraction as follows:

$x_{O_2}=\frac{2}{6.93+3+2} =0.168$

Then, given the following equation:

$P_{O_2}=P_{tot}*x_{O_2}$

So we solve for the total pressure as follows:

$P_{tot}=\frac{P_{O_2}}{x_{O_2}} \\\\P_{tot}=\frac{78.00torr}{0.168} \\\\P_{tot}=465.27torr$

Backpackers often use canisters of white gas to fuel a cooking stove’s burner. If one canister contains 1.45 L of white gas, and

rusak2 [61]

1 L ------- 1000 cm³
1.45 L ----- ???

1.45 * 1000 = 1450 cm³ ( volume )

Density = 0.710 g/cm³

mass = in Kg

m = D * V

m = 0.710 * 1450

m = 1029.5 g

1 Kg ------- 1000 g
kg -------- 1029.5 g

mass = 1029.5 / 1000

mass = 1.0295 Kg

hope this helps!

the atomic mass of magnesium is 24 daltons and the atomic number is 12. a. how many electrons does an electrically neutral magne

vekshin1

Atomic Mass will be 23 the new magnesium formed will be its isotope of magnesium.

We know that,

In stable condition

Number of electrons = Number of protons

Atomic number represents number of proton .

So, here number of proton is 12

Therefore, number of electron is 12

We know that -

Atomic mass = number of protons +Number of neutron

So if magnesium loses one neutron i.e. new number of neutron is 11

then its atomic mass changes.

New atomic mass will be

Atomic mass = $12 + 11$

Atomic mass = 23

This new element with atomic mass 23 and atomic number 12 is the isotope of magnesium.
