Question

8moles of Na2Cr2O2 is how much mass​

Answer 1

`\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 }}}}`
