What is the easiest way to do mole conversions i. e. to grams, molecules, and formula units?

For mole conversion always remember 1 mole of compound = molar mass of compound.

Ex. 2 moles H20 to grams

2mol H2O x 18 g / 1mol H20

For molecules use Avogadro's number like moles multiplied to 6.022x10²³ answer will be in molecules.

Explanation:

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

can i get the brainiest answer

i answered it first

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
