the molal elevation constant is the ratio of ...

the molal elevation constant is the ratio of the rise in boiling point to molality. a true b false

Answer

# Explanation: ## Step1: Recall the formula for boiling - point elevation The formula for boiling - point elevation is \(\Delta T_b = K_b\times m\), where \(\Delta T_b\) is the rise in boiling point, \(K_b\) is the molal elevation constant, and \(m\) is the molality. ## Step2: Rearrange the formula to find \(K_b\) From \(\Delta T_b = K_b\times m\), we can solve for \(K_b\) as \(K_b=\frac{\Delta T_b}{m}\). # Answer: A. TRUE
