The relative formua for Potassium bromide is Kbr
I’m pretty sure the answer is D :)
Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
There are 1000 milligrams in a gram, so you can find the answer through multiplication: 150 • 1000
The answer is 150,000
