<p>is the use of a calculator permitted for the sat II chem test? or are the calculations on the test meant to be done mentally?</p>
<p>You won't need one. Even if you have one, it wouldn't benefit you.</p>
<p>No, not permitted. You're supposed to do it mentally by rounding based on how far apart the answers are.</p>
<p>don't worry, the calculations are very easy. If the periodic system you are given has the exact atomic masses, when using them in calculus, round them to the nearest integer, so it would be mush easy. The difference will be small enough to still be closest to the right answer</p>
<p>oh ok. ty very much.</p>
