Calculate the concentration, in percent by mass, of a refrigerant brine solution which is 4.03 M in NaCl with a density of 1.116 g mL-1. detailed answer, please, i don't understand how to do this at all!!!

A solution contains 4.44% by mass of NaI in water. Calculate the molarity of the NaI, if the density of the solution is 1.2711 g mL-1. i got the answer to be 8.48 M... the percent mass is irrelevant information, right? i figured out the answer just by the...

a car with amass of 1120 kg starts from rest and accelerates to the speed of 17.5 m/s in 18.8 s. assume that the force of resistance remains constant at 402.5 N during this time. what is the average power developed by the car's engine? answer in units of...

thanks a lot guys, i got it!!! :)

wow thanks! its so very clear!

i think a greiger counter

tell people

because of the force caused by you bouncing it

i would just put dear sir or maam or to whom it may concern
