If you're given molar mass in g/mol and also asked to solve something that calls for the molar fixed in mg/mmol, you don't need to do any type of unit conversions! because that example, water has actually a molar fixed of 18 g/mol. This is the very same as 18 mg/mmol. Why? because to get there you need to multiply through 1000 mg/g, and also THEN you have to divide by 1000 mmol/mol (or main point by 1 mol/1000 mmol). The 1000's cancel. So you don't need to waste time doing any kind of conversions.

You are watching: G/mol to mg/mol

Thanks for coming to mine TED talk.

I wish ns remembered this yesterday. The would have actually saved me so much time top top C/P and B/B.

I take it the 12pm test and also there were probably 3 or 4 concerns that would typically require a molarity conversion

Yes!! ns remember this indigenous a S/B explanation ns think. Once I review it i was prefer WHHHHAAT!! great tip

Yeah, that goes without saying but be cautious if you're utilizing a consistent that expresses the in conventional units.

I like to just write every little thing like this:

3mg -> 3e-3g

3ug -> 3e-6g

3ng -> 3e-9g

It's additionally true that change in temperature in C is the same adjust in temperature in K, since 1 unit of C is identical to 1 unit that K. Therefore this functions for any kind of delta T expression. However you have to know precisely when this works, and I would extremely suggest playing it safe due to the fact that they're constantly going to throw in part nonsense conversion.

Apparently the doesn’t walk without saying. Too many of civilization did not recognize this.

Point is, if numerator and also denominator have the same metric prefix, you can transform them both to any kind of other metric prefix and also the numerical value won’t change.

I agree, simplest is to configure everything into exponential notation for just about anything arithmetic ~ above the exam
