Calculate the number of moles 3.15 g of HNO3 19.3 g of NaCl 21.25 g of NaNO3

Answers

The number of moles:
3.15g of $HNO_(3)$
1 mole of $HNO_(3)$ - 63g.
x moles of $HNO_(3)$ - 3.15g
$x=(1\ mole*3.15g)/(63g)=(3.15)/(63)=0.05\ mole$

The number of moles:
19.3 g of NaCl
1 mole of NaCl- 58.44g.
x moles of NaCl- 19.3g.
$x=(1\ mole*19.3g)/(58.44g)=(19.3)/(58.44)=0.33\ mole$

The number of moles:
21.25 g of $NaNO_(3)$
1 mole of $NaNO_(3)$ - 85g.
x moles of $NaNO_(3)$ - 21.25g.
$x=(1\ mole*21.25g)/(85g)=(21.25)/(85)=0.25\ mole$
