8moles of Na2Cr2O2 is how much mass

Margaret [11]

$\boxed{\boxed{\mathfrak{ 1\: mole \:of \:Na_2Cr_2O_2\: = \:it's \:Gram\: Mol. \: mass}} }$

$\underline{ \mathfrak{ Gram \:molecular \:mass \:of \: \red{ Na_2Cr_2O_2}}}$

= 2 × 23 + 2 × 52 + 2 × 16

= 182 grams

1 mole of $Na_2Cr_2O_2$ weighs = 182 g

8 moles weigh = 8× 182

= $\mathfrak{\blue {\boxed{\underline {1456 \: grams}}}}$

or

$\mathfrak{\blue {\boxed{\underline {1. 46 \:kg }}}}$
