# What is the mass in grams of one helium atom?

## What is the mass in grams of one helium atom?

The mass of one helium atom is 6.6×10-24 g.

## What is the mass of 4 moles of helium?

The total mass of four moles of helium (He) is 16.0104 grams.

How many moles are in 4 grams of helium?

one mole
If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams. We can use the molar mass as a conversion factor.

### What is the mass in grams of 6.022 x10 23 atoms AG?

Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g.

### What is mass of helium?

4.002602 u
Helium/Atomic mass

How do you find the mass of a helium atom?

Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4.

#### How many atoms are there in 4 grams of helium?

The atomic mass of Helium is 4 u. Therefore, its molar mass is 4g. This means that the mass of 6.023 X 1023 atoms of He is 4g. Thus there are 6.023 X 1023 atoms in 4 g of He.

#### How many atoms are in 4.0g of helium?

1) The molar mass that is the mass of 6.022 X 10 23 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023 atoms of He.

What is the molar mass of Cu?
