< Question 24 of 25 >

What is the concentration of a 53.50 mL solution of HBr that is completely titrated by 29.00 mL of a 0.200 M

NaOH solution?

[HBr]=

M

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
