Answer:

The discovery of early helium supports the Big Bang Theory because helium is something that would have been a product of a large explosion. Helium is also the most proliferate element in the universe.

Answer:

<h2>Helium was one of the first elements to be formed after the big bang.</h2>

Explanation:

The primitive elements are hydrogen and helium, today a 73% is hydrogen and 25% is helium. All this is comming from the first 3 minutes of the Big Bang, according to scientists. Also, helium functioned as the fuel of stars.

A sample of gas has a mass of 0.0707 grams and has a volume of 48.9 milliliters. What is the density of this gas?
GREYUIT [131]

The density of the gas is 1.45 g/L.

The mass of the gas is 0.0707 g.

The volume of the gas is 48.9 mL.

Density = mass/volume = 0.0707 g/48.9 mL = 1.45 × 10⁻³ g/mL = 1.45 g/L

What is the molar mass of 4.23 g of an elemental gas in a 2.5L container at 282K and 1.4 atm?
balu736 [363]

Answer:

27.98g/mol

Explanation:

Using ideal gas law equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

T = temperature (K)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

According to the information given:

V = 2.5L

P = 1.4 atm

T = 282K

n = ?

Using PV = nRT

n = PV/RT

n = 1.4 × 2.5/0.0821 × 282

n = 3.5/23.1522

n = 0.151mol

Using the formula to calculate molar mass of the elemental gas:

mole = mass/molar mass

Molar mass = mass/mole

Molar mass = 4.23g ÷ 0.151mol

Molar mass = 27.98g/mol
