100g O2 = 3.125 mol O2 (since 1 mol O2 = 32 g) 25 degrees C = 298 K 1.50 atm remains 1.50 atm Gas constant when dealing with pressure in atm is 0.082 Plug these values into the equation: PV=nRT 1.50 atm x V = 3.125 mol x 0.082 x 298 K V = 50.9 FINAL ANSWER: 50.9 L

Use the general 'Ideal Gas' law:

p.V = n.R.T

or

V = n.R.T/p

p=pressure in atm (atmosphere)

V=volume in Litres

n= number of moles

T=absolute temperature in K (= oC + 273)

and R is the general 'gas constant' = 8.02*10-2 L.atm.K-1.mol-1

Or in Standard international units (SI-units):

p=pressure in Pa (pascal)

V=volume in m3

n= number of moles

T=absolute temperature in K (= oC + 273)

and R is the general 'gas constant' = 8.31 J.K-1.mol-1

This is valid for ANY kind of (ideal) gas (at about normal or low temperature, normal or lower pressure; all of the given values are OK)

Use the ideal gas law:

PV=nRT

Pressure(volume) = moles(gas constant)Temperature

When using the ideal gas equation, n=moles. Therefore, the mass needs to be converted to moles to fit the equation:

Grams ÷ molecular mass = Moles

143.6 grams O2 ÷ 32.0 grams = 4.49 moles O2

.450(v) = 4.49(.0821)356

v = 292 L O2

The gas constant is given and remember that temperatures need to be in Kelvin (oC + 273).

Which is more dense 10 grams of chocolate or 100 grams of chocolate?

The density of a material does not change with mass. 100 grams of a material will occupy 10 times the volume of 10 grams of the same material.


What is the volume of 100 grams of oxygen times 2?

The volume depends on the temperature and pressure - neither of which are given.


Why the 100 grams of ice would have a greater volume 100 grams of water?

When the water froze into ice it was expanding (thermal expanision) causing the 100 grams of ice to have a greater volume than 100 grams of water!


Is 100g bigger than 100ml?

grams are mass, ml's are volume apples and oranges.... however at sea level, standard temp (4 deg C) and pressure 100 ml of water has a mass of 100 g. So in that special condition 100 grams would occupy 100 ml and your answer would be no.


How many mL are in 1000 grams of water?

At 4 deg C and at a pressure of 760 mm of mercury, when water is at its highest density, 1000 grams of water will occupy 1000.028 mL. At all other temperatures (pressure = one atmosphere), it will occupy a greater volume. At 100 deg C it will occupy 1043 mL. However, most people will say 1000 grams of water equals 1000 mL.


What is the density of an object that has a mass of 100 grams and a volume of 5 grams?

Impossible to answer. A volume is not measured in grams it is a cubic amount


What is the density of co2 if 0.196 grams occupies a volume of 100 cm?

100 cm is a length, not a volume. However, if the volume were 100 cubic cm, the density would be 0.196/100 = 0.00196 grams per cc.


Explain why the grams of ice would have a greater volume than 100 grams of water?

100 grams is always equal to 100 cubic centimeters?

100 grams of water at standard temperature and pressure has a volume of 100 cubic centimeters or 100 millilitres. The volume of 100 grams of any other substance will depend on its specific gravity or density: if less than that of water, it will have a greater volume; if greater than that of water, it will have a smaller volume.


What is the density if the volume is 100 cm 3?

The density is (the mass, in grams)/100 grams per cm3 .
