a 4.4 g sample of gas occupies 2.24 l of volume at stp. without thinking too hard, what is the mw of the gas, and name two gases
garri49 [273]

As a result, gas's molecular weight is 44g/mol. It is the gas's (Carbon dioxide) molecular weight.

What is Molecular Weight?

The total atomic weights of the atoms in a molecule are measured by its molecular weight. To calculate stoichiometry in chemical equations and reactions, chemists employ molecular weight. M.W. or MW are two frequent abbreviations for molecular weight. Atomic mass units (amu), Daltons, or a unitless expression can be used to indicate molecular weight (Da).

The mass of the isotope carbon-12, which is given a value of 12 amu, serves as the reference point for defining both atomic weight and molecular weight. Because there are many carbon isotopes, the atomic weight of carbon is not exactly 12.

A mole of any gas at STP takes up a volume of 22.4l

at STP, a gas fills a volume of 2.24l

Calculating the quantity of moles of gas in step two

Consequently, the amount of gas in moles

= 0.1 moles

This is equivalent to carbon dioxide's molecular weight.

=44g/mol

As a result, gas's molecular weight is 44g/mol. It is the gas's (Carbon dioxide) molecular weight.

A 1500 L weather balloon is at 'a temperature of 290 K on the ground. As it rises the
myrzilka [38]

Answer:

1086.2 L

Explanation:

The computation of the volume of the elevation is given below:

Here we assume the volume of the elevation be x

As we know that

V¹ ÷ T¹ = V² ÷ T²

Here

V^1 = 1500

T^1 = 290

V^2 = x

T^2 = 210

Now place these values to the above formula

So,  

1500 ÷ 290 = x ÷ 210

x = 1086.2 L
