Jan 16, 2016

Convert moles to gram by multiplying the given amount of moles to the molar mass of CuO.

#### Explanation:

To convert mol Cuo to grams CuO, you simply have to multiply the given number of mol to the molar mass of the compound.

In this case,

molar mass of CuO = $63.546 \frac{g C u}{m o l} + 15.9994 \frac{g O}{m o l}$
molar mass of CuO = $79.5454 \frac{g C u O}{m o l}$

$g C u O = \left(2.50 m o l C u O\right) \cdot \left(79.5454 \frac{g C u O}{m o l}\right)$
$g C u O = 198.86 g$
