Answer:
The number of moles of CO2 is 0,54
Explanation:
We use the formula PV=nRT. The conditions of STP are 1 atm of pressure and 273 K of temperature.
PV=nRT n=PV/RT
n=1 atm x 12 L/0,082 l atm/K mol x 273K
n=0,536049316 moles
9.17 milliliters (mL) of the acid are needed to completely neutralize the base in this reaction.
<h3>What is a neutralization reaction</h3>
A neutralization reaction is a reaction between an acid and a base to produce a salt and water only.
The process of reacting given volume of acids or bases to determine the concentration or volume of either the acid or base required for neutralization is known as titration in volumetric analysis.
The formula to determine the volume of the acid required is given below:
where is the volume of acid required
Concentration of base, Cb = (3.51/74)/0.75 = 0.063 M
Vb = 50. 0 mL
Ca = 0.229 M
Na = 2
Nb = 3
Va = (0.063 * 50 * 2)/(0.229 * 3)
Va = 9.17 mL
In conclusion, the volume of the acid is determined from the concentration, volume and mole ratio of the reaction.

Gram is the unit of weight and it comes under CGS measurement. CGS stands for centimeter for length, gram for mass and seconds for time whereas MKS system contains meter for length, kilogram for mas and seconds for time.
1 gram contains 1000 milligram such as:
For the conversion of gram to milligram,
Thus, 5000 mg is present in 5 g of compound
