Answer
See answer below.
Work Step by Step
a) Converting units:
$3766\ kJ\div 4.184\ kJ/Cal=900.0\ Cal$
b) Proportionally:
$900\ Cal/100.0\ g=1500\ Cal/(x\times 14.0\ g/Tbsp)$
$x=11.9$
12 tablespoons.
c) In one tablespoon:
$900\ Cal/100.0\ g=x/14.0\ g$
$x=126\ Cal$
Water:
$126\ Cal\times4184\ J=m\times4.184\ J/g.K\times (100.0-25.0)$
$m=1680\ g$
