Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:

Putting values in above equation, we get:


Thus, the concentration of NaOH is, 0.336 M
Answer:
If you were speaking of the term mole as a skin condition then a teacher might compare it to a beauty spot. In the position your were speaking of it as an animal they might compare it to mouse a rat or a hamster. In the case you were speaking of a mole as a secret agent then a teacher might compare them to a double agent.
Answer:
The answer is 15 g
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of Chloroform = 1.5 g/ml
volume = 10 mL
We have
mass = 1.5 × 10
We have the final answer as
<h3>15 g</h3>

Answer:
Balance chemical equation is
O2(g) + 2H2(g) --> 2H20(g)
a. 0.20 mol 02 --> 0.225mol H20
b. 0.30 mol H2 --> 2.7mol H20
