35.453 uChlorine / Atomic mass Molecular formula: diatomic chlorine Cl2. Molecular mass according to the periodic table: 35,453 amu. Molar volume: 18,7 cm³/mol. Atomic mass is always equal to the molar mass: 35,453 amu.
How do you find moles of gas?
Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
How do you calculate mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

What is the mass of a gas?
The unit that is used to measure the molar mass is grams per moles (g/mol). The mass of gas in a one-mole sample is equal to the molar mass of gas. If the molar mass of gas X was 40 g/mol, this means that the weight of gas X in a one-mole sample is equal to 40 grams.
What is mole of gas?
A mole is a SI unit for measuring large quantities of subatomic substances like atoms, molecules or smaller particles. A mole of any substance will contain an Avogadro number of molecules. The Avogadro number is equal to 6.02214076 × 1023 . Was this answer helpful?
How do you calculate mass in chemistry?
In this way the formula for the mass of the substance will be : MASS OF A SUBSTANCE = VOLUME X DENSITY.
What is the mass of 0.5 moles of Cl gas?
1 mole of chlorine weighs 35.5 g, therefore, 0.5 mole of chlorine weighs 235. 5=17. 75gm.
How can I calculate my mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
How do you solve for mass?
The mass of an object can be calculated in a number of different ways: mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume. mass=force÷acceleration (m=F/a).
