11.27 mol of carbon dioxide gas is equal to how many liters
saw5 [17]

11.27 mol of carbon dioxide gas is equal to 252.45 L or 270.48 L

<h3>Further explanation</h3>

Given

11.27 mol of CO2

Required

Volume of gas

Solution

If the conditions are assumed to be at the STP state (Standard Temperature and Pressure) at T 0 ° C and P 1 atm, then Vm is 22.4 liters/mol.

so for 11.27 moles the total volume is:

11.27 mol x 22.4 L = 252.45 L

But if the conditions are assumed to be at RTP (Room Temperature and Pressure), Conditions at T 25 ° C and P 1 atm. Vm = 24 liters/mol, then the volume of CO2:

11.27 mol x 24 L = 270.48 L.

How many grams of NaOH do you need to dissolve to make 1.55 Liters of a 1.55 Molar solution?
ale4655 [162]

Answer:

Mass = 96g

Explanation:

Molarity = number of moles/volume of solvent

According to the provided information, volume = 1.55L, Molarity = 1.55M

number of moles (n) = molarity × volume

n = 1.55 × 1.55

n = 2.4025

n = 2.40mol

For NaOH, molar mass = 23 + 16 + 1 = 40g/mol

mole = mass/molar mass

Mass = molar mass × mole

Mass = 40 × 2.40

Mass = 96g
