Mole ratio:

<span>3 Cu(s) + 8 HNO</span>₃<span>(aq) = 3 Cu(NO</span>₃<span>)</span>₂<span>(s) + 2 NO(g) + 4 H</span>₂<span>O(l)

3 moles Cu(NO</span>₃)₂ ----------------- 4 moles H₂O
3.3 moles Cu(NO₃)₂ ---------------- ??

moles H₂O = 3.3 x 4 / 3

moles H₂O = 13.2 / 3

=> 4.4 moles of H₂O

ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with

Kaylis [27]

Answer:

0.57 moles (NH4)3PO4 (2 sig. figs.)

Explanation:

To quote, J.R.

"Note: liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.

H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O

Assuming that H3PO4 is not limiting, i.e. it is present in excess

1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"

The CO2 that builds up in the air of a submerged submarine can be removed by reacting it with sodium peroxide. 2 Na2O2 (s) + 2 C

grandymaker [24]

Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 1.02 atm

V = Volume of gas = 150.0 ml = 0.15 L

n = number of moles of carbon dioxide = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $20^0C=(20+273)K=293K$

$n=\frac{PV}{RT}$

$n=\frac{1.02atm\times 0.15L}{0.0821 L atm/K mol\times 293K}=0.006moles$

$2Na_2O_2(s)+2CO_2(g)\rightarrow 2Na_2CO_3(s)+O_2(g)$

According to stoichiometry:

2 moles of carbon dioxide require = 2 moles of sodium peroxide

Thus 0.006 moles carbon dioxide require= $\frac{2}{2}\times 0.006=0.006$ moles of sodium peroxide

Mass of sodium peroxide needed for 24 hour= $moles\times {\text {Molar mass}}=0.006mol\times 78g/mol\times 24\times 60=674g$

Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.
