Since there is no change in mols on both sides of the equation the mass is constant
OHHHHHHHHH MYYYYYYYYYYYYY GOOOOOOODDDDDDDDDDDD
54g ag *(108mol ag/1 g ag) =5832mol ag
78.6 g (1mol/60.1 g)= 1.31 moles of isopropanol
There are 1000 milligrams in a gram, so you can find the answer through multiplication: 150 • 1000
The answer is 150,000
