48.
Assuming we can use the ideal gas law PV=nRT, we can see that if pressure and temperature are fixed, a gas will assume a volume proportional to the number of moles of that gas present (R is a constant).
Oxygen gas (O2) has a molecular mass of 32, so 1 mole of oxygen has a mass of 32g in that volume, whereas your gas has a mass of 48g (as the volume is fixed, multiply the mass by the density difference) so the molecular weight of your gas is 48 - possibly ozone (O3).

If an insufficient amount of a liquid unknown had been used how would this affect the value of the experimental molar mass?
When the unknown liquid is heated and turned into vapor, the unknown will not occupy the whole container. In the equation to find the molar mass (nRT)/PV, the volume will be greater than the actually volume of the unknown, thus leaving a molar mass that is less than the actual molar mass
What is a example of concentration involving volume and mass?
1 molar NaCl is 58.5 g of salt ( a mass) per liter (a volume).
What is the molar mass of starch?
Gram is a dry measurement of weight and not volume. A cup is usually a measure of volume and not weight. 1 cup is 8oz of liquid. There are about 250 ml in 8 oz.
How do you find no of atoms if molar mass and density is given?
This is actually a chemistry question, but I found it in the math section... well anyways you use an equation with avogadro's number. P(density)=(((#atoms)(molar mass))/((avogadro's number)(volume))). You're solving for #atoms so rearrange the equation. You have density, molar mass, and avogadro's number. As for volume, assuming you know what element this is (which you should know from the molar mass even if it's not given), you should be able to compute volume from the unit cell measurements. If you do not know unit cells... I'm not sure.
How do you prepare 1 molar iodoacetamide solution?
What volume do you want to make. To make 1 liter, you take the 185 g (the molar mass) and dissolve in enough solvent to make the final volume 1 liter.
Which type of stoichiometric calculation does not require the use of molar mass?

If given number of moles volume density and molar volume how do you find the molar mass?
Molar mass is the sum of all of its elements' average atomic mass in grams. Such as: NH4 would be calculated by adding nitrogen's aam (14.007) and hydrogen's aam multiplied by four (1.0079 x 4 = 4.0316). Therefore, ammonium's molar mass would be (14.007+4.0316) 18.039. Rounded to sig figs.
How do you find molar concentration of chemical compounds?
The Stoichiometry of molar concentration follows this simple formula: Mol = Volume (dm³) × Molar Concentration (mol/dm³) Hence: Molar Concentration (mol/dm³) = Number of moles (mol)/ Volume (dm³)

What is molar and molal volume?
The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
How much space will 2.3 grams of sulfur dioxide take up at standard temperature and pressure?
we first find the number of moles( number of moles= mass/molar mass). the we can find the volume by using the formule( volume=number of moles multiplyd by the molar volume)

What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
