**Chemistry Problem: Determining Mass Percent in a Mixture***Question 23 of 30*A mixture contains magnesium nitrate [Mg(NO₃)₂] and potassium bromide (KBr). A 1.85 g sample of this mixture is dissolved in water. An excess amount of sodium hydroxide (NaOH) is added, leading to the formation of a precipitate, magnesium hydroxide [Mg(OH)₂]. This precipitate is then filtered, dried, and weighed, resulting in a mass of 0.465 g. Determine the mass percent of Mg(NO₃)₂ in the original mixture.---*Calculator provided for input:*- Number buttons (1-9, 0)- Decimal point for precision (.)- Sign change button (+/-)- Clear button (C)- Multiplication by 10 option (x 10 □)---**Note:** If you need further resources or explanations, tap or pull up as indicated.

From the stoichiometry calculation, we get mass percent is 63.89%
