How many grams do 5.3•10^26 atoms of sodium weigh

20233.4 g

Explanation:

First, determine the moles by dividing the number of atoms by Avagadro's number.

n= (5.3 × 10^26)/(6.022 × 10^23)

n= 880.106276984

Now determine the mass by multiplying the number of moles by the molecular mass of sodium

m= n × MM

m=880.106276984 × 22.989769

m= 20233.4400033

m= 20233.4 g

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
