Binary molecular compounds would be 2 elements compressed together
Answer:
0.074
Explanation:
15% means that in 100 g of solution 15 g sodium hydroxide is present.
Mass of water = 100 - 15 = 85 g
Number of moles of sodium hydroxide:
Number of moles = 15 g/40 g/mol
Number of moles = 0.375 mol
Number of moles of water:
Number of moles = 85 g/18 g/mol
Number of moles = 4.7 mol
Moles fraction of NaOH:
moles of NaOH/ moles of solvent + moles of solute
0.375 mol/ 0.375 mol+4.7mol
0.375 mol / 5.075 mol
0.074

<u>Answer:</u> The equivalents of B tat are getting used in the given chemical reaction are 2 moles.
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is present in less amount and also it limits the formation of products.
Excess reagent is defined as the reagent which is present in large amount in the chemical reaction.
We are given:
Moles of A = 2 moles
Moles of B = 5 moles
For the given chemical reaction:
By Stoichiometry of the reaction:
1 mole of A reacts with 1 mole of B
So, 2 moles of A will react with = of B
As, given amount of B is more than the required amount. So, it is considered as an excess reagent.
Thus, A is considered as a limiting reagent because it limits the formation of product.
Amount of B used = 2 moles
Hence, the equivalents of B tat are getting used in the given chemical reaction are 2 moles.
