What is the vapour density of the gas if 5.6dm3of a gas weighs 60g at S.T.P?
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.
How many grams barium hydroxide?
get the volume of the chemical and the mass and divide the mass by it's volume
What is density-dependent?
mass density or densityof a material is its mass per unit volume. Mathematically, density is defined as mass divided by volume.
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?
The molar mass of starch can vary depending on its composition, but on average, it is about 162 g/mol. Starch is a complex carbohydrate made up of repeating units of glucose molecules, which contribute to its 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.
What is difference between partial molar volume and specific volume?
Partial molar volume is the volume occupied by one mole of a component in a mixture at constant temperature and pressure, while specific volume is the volume occupied by one unit mass of a substance. Partial molar volume takes into account the presence of other components in the mixture, while specific volume is unique to a single substance regardless of its surroundings.
What is the volume of 7.92g of N2 at SATP?
The volume of a gas at SATP (Standard Ambient Temperature and Pressure) is 24.8 L/mol. To find the volume of 7.92g of N2, you first need to convert the mass to moles using the molar mass of N2 (28.02 g/mol). Then, use the molar volume to calculate the volume occupied by 7.92g of N2.
Is the molar mass of gas dependant on the type of gas?
Yes, the molar mass of a gas is dependent on the type of gas. Each gas has its own unique molar mass based on the atomic or molecular weight of its constituent elements. This value is used to calculate the amount of the gas present in a given volume using the ideal gas law.
What is the ratio of the mass of a substance to the volume occupied by the mass?
Its density.
What is density dependent on?
mass density or densityof a material is its mass per unit volume. Mathematically, density is defined as mass divided by volume.
What element is larger H2o or MgSO4?
Neither H2O nor MgSO4 are elements. They are COMPOUNDS. In terms of volume occupied , MgSO4 is the larger.

What is the relationship between the molar mass and molality of a solution?
The relationship between the molar mass and molality of a solution is that the molality of a solution is dependent on the molar mass of the solute. Molality is calculated by dividing the number of moles of solute by the mass of the solvent in kilograms. Therefore, the molar mass of the solute directly affects the molality of the solution.
What is molar and molal volume?
Molar volume is the volume occupied by one mole of a substance at a specific temperature and pressure, typically measured in liters per mole. Molal volume is the volume of solvent used to dissolve one mole of solute and is typically expressed in liters per mole. Both are important concepts in chemistry for determining the properties of substances and solutions.
The amount of space occupied by mass is called?
That's the "volume".
Is the density of an object how much matter contains?
Not exactly. The density is the mass divided by the volume occupied by that mass. So, it has the units of mass/volume.
