What is the mass of 80 cm 3 of carbon dioxide at S-T-PA- 0-15B- 0-8 gC- 0-4 gD- 0-5 g

The correct option is A 0.15 CO_2 (1 mole) 22400 cm^3 of CO_2 at S.T.P weighs 12 + (16) × 2 = 44g ∴ 80 cm^3 of CO_2 at STP weighs = 44/22,400× 80 = 0.15 gms ...

Solution

The correct option is A
0.15

$C O_{2}$ (1 mole)

$22400 c m^{3}$ of $C O_{2}$ at S.T.P weighs 12 + $(16) \times 2$

= 44g

$∴$ $80 c m^{3}$ of $C O_{2}$ at STP weighs $= \frac{44}{22, 400} \times 80$

= 0.15 gms
