Question

) Numericals: i. The mass of an electron is 9.11x10-31. Convert it in gm, milligram, microgram​

Answer 1

Answer:

You start with the value you’re wanting to convert, in this case, kg. Put it over 1. In science, everything we do is in fractions, so get used to it. The parentheses indicates that you’re multiplying. And in that set of parentheses, we’re going to compare the kg to the thing we want to convert to, g. Since 1 kg = 1000 g, ALWAYS, ALWAYS, ALWAYS put the thing you WANT to find on top. That way, your units will cancel and you’re actually left with the thing you wanted to find. Then just multiply it out.
