What volume ( L ) of carbon dioxide, CO2, is required to produce 3.75 moles? 1 mol = 22.4 L
Allushta [10]

Assuming the number of moles give is of CO₂, since we know that 1 mol is equivalent to 22.4 L in this case, we can use rule of three to answer this:

V ---- n

x ---- 3.75 mol

22.4 L ---- 1 mol

So, we have the follwing relation:

\begin{gathered} \frac{x}{22.4L}=\frac{3.75}{1} \\ x=3.75\cdot22.4\cdot L \\ x=84L \end{gathered}

So, we need a volume of 84 L.

Calcium hydroxide is titrated with nitric acid. What volume of 0.0200 M calcium hydroxide is required to neutralize 35.00 ml of
gogolik [260]

Answer:

43.75 ml

Explanation:

Given that the equation of the reaction is;

2HNO3(aq) + Ca(OH)2(aq) ---> Ca(NO3)2(aq) + 2 H20(l)

Concentration of acid CA= 0.05 M

Concentration of base CB = 0.02 M

Volume of acid VA = 35.00ml

Volume of base VB= ???

Number of moles of acid NA= 2

Number of moles of base NB=1

From

CAVA/CBVB= NA/NB

Making VB the subject of the formula;

VB= CAVANB/CBNA

VB= 0.05 × 35 × 1/ 0.02 × 2

VB=1.75 /0.04

VB= 43.75 ml
