[SAT2400]

Unit for Molar Mass(M)??

Homework Statement

What's the unit for Molar mass? Is it different in CHemistry and Physics?

Homework Equations

PV=nRT

The Attempt at a Solution

In Chemistry class(last year) I think I used (g/mol).
But in Physics, my teacher says it's (kg/mol).
What is right??

In Physics, the SI unit for mass is the Kg. In chemistry, it usually is grams but it also depends on the type of questions you do and what S! unit the question asks for.

g/mol, kg/mol, slugs per mol, and (whatever other mass unit) per mol are all fine for both physics and chemistry. However, it may be more convenient to use a certain unit for certain calculations.

It is like asking which is a 'correct' pressure unit - PSI, atm or Pascal.

In your assignments and tests, use whichever you feel more comfortable with. Then just convert the answer to the units your teacher wants. There is no "correct" unit here, just your teacher's personal preference.

If you are careful to always make sure your units check out and cancel properly, there should be no problem.
