11. if there are 8.24 x 1022 molecules of nacl in a salt shaker, what is the mass of the salt?
8.00 a nacl

8.12 g NaCl

Explanation: Use Avogadro's number to find the number of m

moles of NaCl:

8.24x10²² molecules NaCl / 1 mole NaCl/ 6.022x10²³ molecules NaCl

= 0.14 mole NaCl

Next convert moles to grams NaCl using its molar mass;

0.14 mole NaCl x 58g NaCl / 1 mole NaCl

= 8.12 g NaCl

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
