How do i find the grams in 1.26 x 10-4 moles of hc2h3o2 (and just the grams in moles of anything if you don't mind explaining.)

Find the number of moles of argon in 364g of argon.

These traits describe either a chemical or a nuclear reaction. which statements describe a nuclear reaction? check all that apply. involves the loss, gain, or sharing of electrons may involve a change in total mass involve relatively low energy changes occur outside the nucleus involve very high-energy changes involve changes in nuclides when decay occurs

Suppose that a large mixing tank initially holds 300 gallons of water in which 50 pounds of salt have been dissolved. pure water is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at the same rate. determine a differential equation for the amount of salt a(t) in the tank at time t 0. what is a(0)?
