<p>I know ap chem doesn’t allow calculators on the mc but was that true for the older tests? specifically the 1989 one which I’m doing for practice. I hate it when i get stuff wrong b/c of a bad estimation. Its a pain doing Pv=nrt w/o a calc. I’m talking about questions like this:</p>
<li><p>How many grams of calcium nitrate, Ca(NO3)2, contains 24 grams of oxygen atoms?</p>
<p>(A) 164 grams
(B) 96 grams
(C) 62 grams
(D) 50. grams
(E) 41 grams </p></li>
</ol>
<p>I could do it but its annoying and it seems kinda pointless for collegeboard to not allow a calc for it.</p>
