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

No, I am confused because in the answer is 1.8 x 10^-9g, from my revision guide.

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?
