Q2) Cint=0.3530M Vint=0.1 Cfin=? Vfin=0.5 n=Cint×Vint =0.0353moles so 0.0353moles=Cfin×Vfin Cfinal=0.0353moles÷0.5 Cfin=0.0706mol × 3 Final con.=0.2118mol/L

he's about 65 I'm guessing... you could probably guess he's very old fashioned in his teaching methods thanks for the help!

thanks for the help - its probably argon

I'm having problems with questions like this... I'm sure how to go about solving it... an explaination to the working out would help. thanks Calculate the volume of gas occupied by 3.6426 g of nitrogen at 45.00oC and 101.3 kPa given that value of the gas constant, R, is 8.314 J/K.mol.

I need some help solving this question... an explaination would be extremly helpful.. thanks Calculate the volume occupied by 0.0950 mol of calcium phosphate at 25oC and 101.3 kPa, given its density at this pressure and temperature is 3.14 g/mL.

Thanks... that really helped me out

I can't get the right answer for this question: Calculate the concentration of anions in a solution prepared by dissolving 0.585 grams of nickel(II) bromide in sufficient water to produce 100.0 mL of solution. any help/explaination would be great thanks
