Answer:
[tex]\Large \boxed{\sf 34.2 \ g}[/tex]
Explanation:
Mole ratio
[tex]9:4[/tex]
[tex]1.75:x[/tex]
Moles of CO₂
[tex]\displaystyle \frac{4 \times 1.75}{9} =0.78[/tex]
Use formula to find mass
[tex]\displaystyle moles=\frac{mass}{M_r}[/tex]
Relative molecular mass of CO₂ = 12 + 16 × 2 = 44
[tex]\displaystyle 0.78=\frac{mass}{44}[/tex]
[tex]mass=34.2[/tex]
