Question

how many molecules are there in 66 g of CO²?​

Answer 1

Answer:

co2 means carbon or oxiode

Explanation:

carbon have 12 molecules and oxide have 16 molecule and2 is the power of o2 so all 12+16×2 total are 44 u molecule

Answer 2

Answer:

The number of moles in 66 gram of carbon dioxide molecules is 1.5.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23}6.023×10

23

of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}Number of moles=

Molar mass

Given mass

Given mass = 66 g

Molar mass = 1(12)+2(16)=44 g/mol1(12)+2(16)=44g/mol

Putting in the values:

\text{Number of moles of carbon dioxide}=\frac{66g}{44g/mol}=1.5molesNumber of moles of carbon dioxide=

44g/mol

66g

=1.5moles

Thus there are 1.5 moles of carbon dioxide
