Answer a is the correct one
In order to calculate the energy required, we must first know the specific heat capacity, or the amount of energy required to raise the temperature of a unit mass of substance by 1 degree Celsius, of water. This, at 1 atm pressure, is 4.18 joules per gram.
Next, we use the formula:
Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity and ΔT is the change in temperature.
Q = 435 * 4.18 * (100 - 25)
Q = 136.4 kJ

<span>4.5x10^22
Because there are 6.022x10^23 atoms per mole; therefore,
(6.022x10^23*(0.075)=04.5x10^22 atoms of titanium.</span>
