Chem (: how many grams do 1.3 x 10^21 atoms of sodium weigh?

look at yo periodic table to find the atomic mass

it says that there is 22.98g of sodium (Na) in 1 mol of sodium

1 mol is 6.022 * 10^23 atoms

one way we can do this is ratio and proportion

we are solving for

multiply both sides by

let's say =22.98g and and

therefor

so it weighs about

answer: 1+1

step-by-step explanation: 1+1 is at least 2
