Element X has two isotopes. One has a mass of 10.0 amu and an abundance of 20.0%.The other has a mass of 11.0 amu and an abundance of 80.0%. Estimate the average atomic mass.What element is it?
Step 1 of 3
CH 111 Notes: Week 8 If 25.0 g Cu at 90.0ᵒC is placed in 100.0 g of water at 20.0ᵒC, what will the final temperature of the water be (c p(Cu)= 24.4 J/mol*ᵒC) o Assume T final the same for both Cu and H O 2 o Assume container absorbs negligible heat → q Cu= -q H2O o 25.0 g Cu (1 mol Cu/63.55g) = 0.3934 mol Cu 100.0 g H 2 (1...
