Question

volume of 4.4 gm co2 at NTP

Answer 1

Answer:

The volume of 4.4 gm Co2 at NTP is 2.24 litres.

Explanation:

First we have to calculate the molecular mass of CO2, Which will be 12 +16 x 2= 44g.

Now If 1 mole of CO2 has 44g of molar mass

So, Number of moles in 4.4g will be 4.4/44 = 0.1 moles

1 mole is equal to 22.4 liters at NTP

Therefore, 0.1 moles = 0.1 x 22.4 = 2.24 liters at NTP (NTP is normal temperature and pressure). Normal temperature is 25ᵒC and normal pressure is 1 atm which is 101325 Pascal and 22.4L is the molar volume.

Answer 2

Thus the volume of 4.4 g of CO2 is 2.24 L

Explanation:

We are given that:

• Mass of CO2 = 4.4 g
• To Find = Volume = ?

Solution:

We need to find the molar mass of CO2 first.

CO2 = 12 + 16×2 = 12 + 32 = 44 g

Now, 1 mole of CO2 = 44 g   --------(1)

Volume of 1 mole of CO2 = 22.4 L ( at S.T.P) -------(2)

From equation (1) & (2)

44 g = 22.4 L

1 g = 22.4/44

So, 4.4 g = 22.4 × 4.4 / 44 = 2.24 L

Thus the volume of 4.4 g of CO2 is 2.24 L
