1.
calculate the ph of a mixed solution of 0.4M acetic acid and 0.6M sodium
acetic. the Ka for acetic acid is 1.8乘10的負五次方
(log0.67=-0.17 log1.5=0.18 log1.8=0.26 )
2.If 325 ml of 0.333M Nacl is diluted to 2.00L with pure water, what is the
molar concentration of Nacl in the diluted solution?
3.The radius of a lithium atom is 152 pm. what is this in meter?
拜託大家幫個忙 @@
