Answer: The final pressure is 116kPa or
Explanation:
The combined gas equation is,
where,
= initial pressure of gas =
= final pressure of gas = ?
= initial volume of gas = v ml
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The final pressure is 116kPa or
Answer:
3.75 mole
Explanation:
molecular mass of NaOH = 39.97 gm
i.e,
==>39.97 gm NaOH contains 1 mole of NaOH
==>1 gm of NaOH contains 1/39.97 mole of NaOH
==>150 gm of NaOH contains (1/39.97) *150 mole of NaOH
==>150 gm of NaOH contains 3.75 mole of NaOH.
The chemical reaction would be written as:
2Na + Cl2 = 2NaCl
Since we are given the amounts of the reactants available for reaction, we have to determine the limiting reactant. And use this amount to calculate for the theoretical yield.
55 g Na ( 1 mol / 22.99 g ) = 2.39 mol Na
67.2 f Cl2 ( 1 mol / 70.9 g ) = 0.95 mol Cl2
Therefore, the limiting reactant would be Cl2 since it is the one consumed completely.
0.95 Cl2 ( 1 mol NaCl / 1 mol Cl2) = 0.95 NaCl produced from the reaction
Hey there!
Ba(NO₃)₂
Ba: 1 x 137.327 = 137.327
N: 2 x 14.007 = 28.014
O: 6 x 16 = 96
-----------------------------------
261.341 g/mol
The molar mass of Ba(NO₃)₂ is 261.341 g/mol.
