For #1 I think-
20/10.00
149.89X20=2997.8 (not sure)
Round your answer to the correct number of significant digits and show work.

molarity=mass/(molmass*volumeinLiters)
a. mass=molarity*molemass*volumeinLiters
b. see definition above on Molarity
c.moles= molarity*volumeinliters
a. mass=molarity*molemass*volumeinLiters
b. see definition above on Molarity
c.moles= molarity*volumeinliters
