The molar volume of a gas at STP (standard temperature and pressure) is 22.4 L/mol. To calculate the molar mass of the gas, you can use the formula: Molar mass = (mass of gas / volume of gas) x molar volume at STP. In this case, with a mass of 60g and a volume of 5.6 dm3, the molar mass would be 60g/5.6dm3 x 22.4L/mol = 240 g/mol. Vapour density is calculated as 2 x molar mass, so in this case the vapour density would be 480 g/mol.
At standard temperature and pressure (STP), the molar volume of a gas is approximately 22.4 L. To find the volume of 150g of ozone (O3) at STP, you would first convert the mass of ozone to moles, then use the molar volume to find the volume.
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.
To calculate the volume of chlorine gas produced, you need to know the molar mass of chlorine and use the ideal gas law equation. First, convert the mass of chlorine gas to moles using its molar mass. Then use the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature. Finally, you can solve for V to find the volume in liters.
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
when you use volume to fill a fish tank/bowl.
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.
Use Boyle's law
You can find molar volume by dividing the volume of a gas by the number of moles of gas present. The equation to calculate molar volume is V = nRT/P, where V is volume, n is the number of moles, R is the ideal gas constant, T is temperature, and P is pressure.
To determine the number of moles in a substance based on its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.
To determine the number of moles in a substance when given its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.
To find moles from volume in a chemical reaction, you can use the formula: moles volume (in liters) / molar volume (22.4 L/mol at standard conditions). Simply divide the volume of the gas by the molar volume to calculate the number of moles present in the reaction.
Volume-volume stoichiometric calculations do not require the use of molar mass, as they involve the relationship between volumes of reactants and products in a chemical reaction. This type of calculation is commonly used when dealing with gases at standard temperature and pressure.
To determine the number of moles in a substance using its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). Molar volume is a constant value that depends on the substance being measured.
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
Write a balanced chemical equation for the reaction Convert the given volume of the starting substance to moles using its molar volume Use the mole ratio from the balanced equation to find the moles of the desired substance Convert the moles of the desired substance to volume using its molar volume
For example, many liquids are sold by volume (such as, "please sell me a liter of milk").
