To enter a number in scientific notation, remember to use the "enotation". For example, Avogadro's number would need to be enteredas 6.02e23. Note that there are no spaces. For a negative exponent,place the negative sign after the e, like in 6.02e-23 (no spaces).Numbers in scientific notation should be entered with at least twoplaces past the decimal point.
1__________atoms

Explanation / Answer

Part a Number of atoms will be the one with the number ofmoles. 1 mol - 6 X 10^23 molecules, so basically ust find which onehas the most moles and that is the highest Moles = grams/MW a) 1.5 moles b) 80 grams of K is equal to 2 moles of K, from periodictable c) 50 grams Ne is equal to 2.5 moles d) 21 grams Carbon is equal to 1.75 moles so the orderis From least to greatest a d b c 2) 1 mol has 6 X 10^23 molecules. This is avogado's number sojust multiply these two numbers together to get the answer: Answer is 2.76 X 10^21 molecules 2) 1 mol has 6 X 10^23 molecules. This is avogado's number sojust multiply these two numbers together to get the answer: Answer is 2.76 X 10^21 molecules
