Question

Find out number of moles present in220 g of CO2.(atomic mass of C=12,O=16)​

Answer 1

Heya!!

━━━━━━━━━━━━━━━━━━━━

Question about:- The given question is based on topic Moles.

Answer:-

Given,

• Mass of Co2 is 220g

To Find:-

• The No.moles present in Co2

Calculations:-

Number of moles = $\frac{Mass\:of\:Co2}{Molecular \:mass\:of\:Co2}$

Molecular mass

= C(12)o2(26) = 12+(16×2)

Molecular mass of CO2 = 44 g.

NOW,

No.of moles = $\frac{220}{44}$

=5

No.of moles present in 220 g of Co2 is 5.
