## What is the weight of 0.5 moles of oxygen gas?

0.5 moles of O2 weighs 16 grams.

## What is the mass of 0.1 mole of oxygen?

Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.

## What is the mass of 1.5 mole of O2?

Mass of oxygen molecule = 2 * molar mass of oxygen = 2 *16 gm per mol =32gm per mol Since mass of 1 mol of oxygen molecule = 32gm Thus, mass of 1.5 mol of oxygen molecule= 1.5 * 32gm = 48gm.

## How many oxygen atoms are there in 0.5 mole of oxygen gas?

(i)0.5 mole of oxygen gas. (ii) 3.011 x 1023 atoms of oxygen.

## What is the weight of 0.5 mole?

The molecules of water have hydrogen bonding and thus, for another substance to be soluble in water molecules shall form hydrogen bond with water. Mass of 0.5 mole of water is 9g. Note: Molecular mass is the mass of the molecule and molar mass is the mass of a mole of a substance.

## What is the volume of 0.5 mole of oxygen at STP?

1 mole of a gas occupy =22.4L volume at STP therefore, 16gO2 gas =0.5 mole of O2 gas will occupy =0.5×22.41=11.2L at STP.

## What will be the number of oxygen atoms in 0.1 mole of o2?

A mole of oxygen molecules contains 2 moles of oxygen atoms. Thus “1 mole of oxygen molecules” means 6.022 x 1023 O2 molecules, or 2 x 6.022 x 1023 O atoms; “1 mole of oxygen atoms” means 6.022 x 1023 O atoms.

## What is the mass of 2.5 mole of Cl2?

Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.

## How many molecules are there in 1 mole of oxygen?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many moles of electrons weigh 1kg?

Or, 1 kg will contain = \$dfrac{1}{{9.108 times 6.022}} times {10^8}\$ moles of electrons. Thus, \$dfrac{1}{{9.108 times 6.022}} times {10^8}\$ moles of electrons will weigh one kilogram. So, the correct answer is “Option D”.

## How many moles of oxygen atoms are present in 0.5 moles of BaCO3?

0.5 moles of barium carbonate BaCO3 Contain 3x moles of O atom. That is 1.5 moles. It shows that 1.5 moles of oxygen are present in 0.5 moles of barium carbonate.

## How many grams are in 0.5 moles of H2SO4?

molar mass of H2SO4 is 98g. given mass or mass present =0.5 × 98 = 49g.
