A student needs 500 mL of a 1.5 M solution of NaCl for an experiment. How many moles of NaCl should she use?

She should use 0.75 mol.

Explanation:

By definition, molarity (M) is the number of moles of solute per liter of solution. One liter of solution is equal to 1000 mL.

Therefore,

1000 mL 1.5 moles of NaCl

500 mL x= 0.75 moles of NaCl

The moles contained in 500 mL of a 1.5 M NaCl solution are 0.75.

air

in a tire you fill a tire with air

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

hope this mark me brainliest
