Determine the formula weight of caffeine, C₈H₁₀N₄O₂. Provide an answer to two decimal places.

arlik [135]

Let's find

$\\ \tt\hookrightarrow C_8H_10N_4O_2$

We need accurate mass

$\\ \tt\hookrightarrow 8(12.011)+10(1.007)+4(14.006)+2(16.0)$

$\\ \tt\hookrightarrow 96.088+10.07+56.024+32.0$

$\\ \tt\hookrightarrow 196.182g/mol$

$\\ \tt\hookrightarrow 196.18g/mol\:or 196.18u$
