Question

How many grams are equal to 0.11 mole of copper(I) chromate?

Answer 1

Mass of Copper(I) chromate( CuCrO₄) = 19.75 g

Further explanation

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

`\tt \large{\boxed{\bold{mol=(m(mass))/(MW(molecular~weight))}}`

0.11 mole of Copper(I) chromate( CuCrO₄) ⇒ MW=179.54 g/mol, so mass :

`\tt mass=mol* MW\\\\mass=0.11* 179.54\\\\mass=19.75~g`
