How many atoms are in 1.50 moles lead?

More specifically, you need to have exactly 6.022⋅1023 atoms of an element in order to have one mole of that element – this is known as Avogadro’s number. In your case, you must determine how many moles of lead would contain 1.50⋅1012 atoms of lead.

How many moles are in 5 grams of lead?

How many grams Lead in 1 mol? The answer is 207.2. We assume you are converting between grams Lead and mole.

How many atoms are in 4 moles helium?

– So, the no of atoms in 4 moles of helium is 2.4088 × 10²⁴.

How many atoms are in 2 moles?

after the 19th-century chemist Amedeo Avogadro, is the number we use in chemistry to represent macroscopic amounts of atoms and molecules. Thus, if we have 6.022 × 10 23 O atoms, we say we have 1 mol of O atoms. 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 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.
