to form CO2 and 0.50 g of the carbon combusts to form Co.
The resultant mixture of CO2 and CO is passed through excess NaOH(aq) and the remaining gas
is then dried and collected.
What is the volume of the remaining gas? (All gas volumes are measured at 25°C and
1 atmosphere pressure.)
A 1 dm
B 1.5 dm3 C2 dm
D 3 dm

PLEASE MARK AS THE BRAINLIEST AND THANK YOU FOR ASKING

Answer 2

Answer:

Explanation:

so the answer is 1dm3 soo u get that answer by,

first u have to get the moles of 0.5 grams of carbon which is 0.0417moles

then u have to find the volume of carbon by multiplying the moles by 24

0.0417 x 24 = 1 dm3 (A)
