Answer:
0.1 dm³.
Explanation:
To obtain the value of 100 cm³ in dm³, do the following:
Recall:
1 cm³ = 0.001 dm³
Therefore,
100 cm³ = 100 cm³ × 0.001 dm³ / 1 cm³
100 cm³ = 0.1 dm³
Thus, 100 cm³ is equivalent to 0.1 dm³.
I would say is b. The answer
<span>Weight of CaC2 is 1.53 g
Temparature is 23 celcius T = 23 + 273K = 296K
The pressure of the gas P = 755 torr
Calculating the moles of CaC2 n = 1.53g x 64.0994 mol/g = 0.023869 moles
PV = nRT
V = nRT / P => V = (0.023869 mol) x (62.3636 L Torr / K mol) x (296 K) / 755 torr
Volume of C2H2 = 0.587 L</span>
