## How many moles are in 2g of ch4?

2grams of CH4 = 1/4 mole particles. Hence, 2g of methane would have 1/4 moles of particles.

## What is mass of 2.5 moles of methane?

Dharmaraj answered this. Mass of 1 mole of methane = 12 + 4 = 16 u Mass of 2.5 mole of methane =x x= (16 × 2.5) x = 40 u OR Mole = mass of substance ÷ molar mass 2.5 = mass of substance ÷ 16 Mass of substance = 16 × 2.5 = 40 u.

## How many atoms are there in 0.2 mol of methane molecules CH4?

Explanation: Each methane (CH4) molecule has 4 hydrogen atoms. 1 mole of anything has 6.022 X 10^23 molecules (Avagadro’s number).

## How many particles are there in 2 mol of Na?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

## How do you find the mass of two moles?

The molar mass of a substance is the mass of one mole of that substance. It is equal to: the relative atomic mass or A r in grams for atoms and metals. the relative formula mass or M r in grams for molecules and compounds.

Molar mass.

Substance Oxygen O 2 M r = 2 × 16.0 = 32.0 32.0
