Answer:
70g Na
Explanation:
The sodium reacts with water as follows:
2Na + 2H2O → 2NaOH + H2
<em>Where 2 moles of Na produce 1 mole of H2.</em>
To solve this question we must find the moles of H2. With the balanced equation we can find the moles of Na and its mass as follows:
<em>Moles H2:</em>
PV = nRT; n = PV/RT
<em>Where P is pressure = 1atm,</em>
<em>V is volume = 34L,</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 273.15K = 0°C</em>
Replacing:
n = 1atm*34L/0.082atmL/molK*273.15K
n = 1.52 moles H2
<em>Moles Na:</em>
1.52 moles H2 * (2mol Na / 1mol H2) = 3.04 moles Na
<em>Mass Na-Molar mass: 22.99g/mol-</em>
3.04 moles Na * (22.99g / mol) =
<h3>70g Na </h3>

There are four fundamental forces existing in the universe so called universal forces. They are the strong nuclear force, the weak nuclear force, the electromagnetic force and the gravitational force. The strong nuclear force is the strongest force acting while gravityis weakest.
