The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO

Black_prince [1.1K]

CO₂ + H₂O -------> H₂CO₃

moles of CO₂ = $\frac{MASS of Carbon}{ MOLAR MASS}$

= $\frac{528 g}{44.01 g / mol}$

= 11.997 mol

mole ratio of CO₂ : H₂O =   1 : 1

  ∴ moles of H₂O = (`11.997 mol ) * 1
= 11.997 mol
   ≈ 12 mol

mariarad [96]

A. PV=constant
752 torr = 0.989 atm
(0.989 atm)(4.38 L) = (1.88 atm)V
V = 2.30 L

B. T/V = constant
(294 K)/(4.38 L) = (448 K)/V
V = 6.67 L

Hoped this helped ( I believe it's right, sorry if it's not )

alina1380 [7]

P₁ = 0.90 atm

V₁ = 50.0 mL

T₁ = 298 K

P₂ = 1 atm

T₂ = 273 K

V₂ = P₁ x V₁ x T₂ / T₁ x P₂

V₂ = 0.90 x 50.0 x 273 / 298 x 1

V₂ = 12285 / 298

V₂ = 41 mL
