PLEASE HELP ILL CHOOSE BRAINLIEST I REALLY NEED THE HELP. Tungsten hexaflouride is a very heavy gas (MM=297.8/mol) Find the molar mass the diatomic gas that effuses through a proud plug about 2.8 times faster than the WF6 at the same temperature and pressure? What is the identity of this diamotic gas?

Calculate the molarity of each of the following solutions. part a) 0.12 mol of lino3 in 5.5 l of solution part b) 60.7 g c2h6o in 2.48 l of solution part c) 14.2 mg ki in 100 ml of solution

Given the following equation: 2a1 + 3mgcl2 --> 2alcl3 + 3mg how many moles of aluminum chloride are produced from 2.5 moles of magnesium chloride?
