    Okay, from the equation, you know that 3 mol of BaCl2 gives 1 mol of Ba3(PO4)2

    So, can you find the number of moles of BaCl2?

    Hint Num. of moles = Mass/Relative atomic mass

    Then, find the number of moles of Ba3(PO4)2

    When done, use the equation again to find the mass of it that is formed. Can you post what you got so that we make you you got it right? :)
