Explanation:
firstly find for the molar mass of kcl and molar mass of k
and then
molar mass of k = x
molar mass of kcl= 40
cross mutiply and then simplify you will get your answer
Answer:
the radius is half the diameter
Answer:
use n=m/M (moles=mass/molar mass) to find out how many moles of C2H6 there are in 60g
Explanation:
I googled it, here it is lol
Mass number - # of protons = #neutrons, so I would say the answer is 5
