It's urgent How would you find the number of 'chalk molecules' it takes to write your name on the board What would i need to do?

To find the number of chalk molecules it takes to write your name on the board, first measure the length of your name in centimeters. Next, estimate the thickness of the chalk line you would draw, then calculate the volume of chalk used by multiplying the length by the thickness. Finally, divide this volume by the volume of a single chalk molecule to determine the total number of molecules needed. You may need to use the density of chalk and the molecular weight to find the volume of one molecule.
