Well, what are the molar masses of potassium, chromium, and oxygen individually...?

Explanation:

And a quick glance at the Periodic Table tells you...

$C r, 52.00 \cdot g \cdot m o l^{- 1}$ $Cr, 52.00*g*mol^-1$

$K, 39.10 \cdot g \cdot m o l^{- 1}$ $K, 39.10*g*mol^-1$

$O, 16.00 \cdot g \cdot m o l^{- 1}$ $O, 16.00*g*mol^-1$ .

You simply add these masses appropriately to get the molar mass of the compound. Note that compound itself is PROBABLY $K_{2} C r_{2} O_{7}$ $K_2Cr_2O_7$ , or $K_{2} C r O_{4}$ $K_2CrO_4$ .... $K_{2} C r_{2} O_{2}$ $K_2Cr_2O_2$ as written is a bit suspect...
