(a) Explanation Given The molarity of first KBr solution is 1 .00 M . The volume of first KBr solution is 35 .0 ml . The molarity of second KBr solution is 0 .600 M . The volume of second KBr solution is 60 .0 ml . Formula The number of moles of first KBr solution is calculated by the formula, M = n V ( mL ) × 1000 mL n = M × V ( mL ) 1000 mL Here, V is the volume of first KBr solution M is the molarity of first KBr solution. n is the moles of first KBr solution. Substitute the values of M and V in the above formula. n = 1.00 M × 35.0 ml 1000 ml = 0.035 mol Hence, the number of moles of first KBr solution is 0 .035 mol . The number of moles of second KBr solution is calculated by the formula, M = n V ( mL ) × 1000 mL n = M × V ( mL ) 1000 mL Here, V is the volume of second KBr solution M is the molarity of second KBr solution. n is the moles of second KBr solution. Substitute the values of M and V in the above formula. n = 0.600 M × 60.0 ml 1000 ml = 0.036 mol Hence, the number of moles of second KBr solution is 0 .036 mol . The total number of moles of KBr is equal to the total number of moles of first KBr solution and number of moles of second KBr solution. Total number of moles of KBr = ( 0.035 + 0.036 ) mol = 0 .071 mol Heating will not affect the quantity of KBr in the solution because on heating only water will evaporate. The chemical equation for the reaction between silver nitrate ( AgNO 3 ) and potassium bromide ( KBr ) is, AgNO 3 ( a q ) + KBr ( a q ) → AgBr ( s ) + KNO 3 ( a q ) Here, moles of KBr is equal to the moles of AgNO 3 Therefore, 0
