    So you have the mass of one bacteria. They want the mass of 3x10^6 bacteria.
    Any idea what operation you need to use?

    That answer looks correct to me.
    So if we remove the standard for aspect of the question then think about it like this:
    The mass of one bacteria is X
    What is the mass of 283 bacteria?
    Would you know where to start then?
