## What is the mass of 0.5 of N?

Hence the mass of 0.5 moles of nitrogen atom is **7g**.

## How do you find the mass of 0.5 mole of nitrogen?

mass of one mole of nitrogen gas is 28 gram(14*2) mass of 0.5 mole of nitrogen is **14 grams**.

## What is the mass of 0.5 mole of n2?

mass of 1 mole of nitrogen gas (N₂ ) = 14 * 2 = 28 gram. therefore mass in 0.5 moles is , = 28 * 0.5. = 14 .0. therefore mass of 0.5 moles of N₂ = **14 grams** .

## What is the mass of 5 mole molecules of nitrogen?

The mass of 5 moles of nitrogen gas is **112 grams**.

## What is the mass of 0.2 mole of n2?

Mass of nitrogen gas= 14gram. 0.2 moles= 14×0.2. = **2.8gram**.

## What is the mass of 0.2 mole of nitrogen gas?

m=M×n=28×0.2=**5•6g**.

## What is the mass of 0.5 moles of CaCO3?

Solution — Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.

## What is the mass of 0.5 mole of 03 molecules?

∴ 0.5 mole of ozoneO3 = 0.5 × 48 /1 = **24 g**.

## How many nitrogen atoms are there in 0.5 moles of nitrogen?

6. **022×1023 atoms**.
