Answer:
Molar mass = 103.0 g/mol,
0.728 mol NaBr
Explanation:
Molar mass M(NaBr) = M(Na) + M(Br) = 23.0 + 80.0 = 103.0 g/mol
75.0 g NaBr * 1 mol NaBr/103.0 g NaBr=0.728 mol NaBr
Answer:
True
Explanation:
When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. Because the base "soaks up" hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions. This kind of solution is alkaline.
