Answer 1

well 60/16 is the moles and 40/120 is a third, i would say the answer of 60/16 mult by a third.

Answer 2

these are ratio problems kind of like this 1mole of water/16 g= x mole of water/60 g = 60/16 = moles of water then that answer/120 ml = how many moles/40 = 40(that answer)/120= how many moles in 40

Answer 3

16 x 3.75 = 60 so 3.75 moles

Answer 4

1g H20 in 2mL soln
=>
20 g H2O in 40mL soln
=>
20g/16g/mol
