I was actually not looking for any in depth answers, but just some yes or no's to help me clear some things in my head.
Briefly, we don't do that here. The forum rules specify, we don't give out free answers, write lab discussions for you, etc. We do Socratic learning here -- you ask a question, we answer with a question, that leads to an answer, so you learn new things -- it's less like cheating, and you learn more that way, and are better off on exams. And this board ends up less attractive to people who don't want to learn, and more attractive to people with interesting things to talk about.
What does you lab writeup or text book tell you about the enzyme lactase, and Benedict's solution? And can you use that info to work out your problem yourself, or is there some small point that's confusing that we can help with.
And this ambient light thing, why do you keep mentioning it? This is a bog standard, high school level assay, developed a century ago. It's never done without light, because humans can't see a precip. without light. Is this a question on your lab practical, or are you trying to explain away an anomalous result with a "maybe sunlight did it" bit of handwavium, like this unfortunate person here:

the amount of precipitate is not that important, but having it or not is.
I should have specified concentration anyways,
10% Lactose, 2% Lactase
2. If yes, roughly how much of precipitate would I get in terms of milligrams with those kind of values.
Pick one.
