Answer:
C + O2 ⇒ CO2
mole of O2: 18.6/32=0.58125= mole of CO2
⇒ gram of CO2: 0.58125*(12+32)=25.575
Explanation:
Answer:
molarity = moles of solution/liters of solution
molarity = 1 mole/2 liters
molarity = 0.5 M
molarity = 50 moles/200 kg
molarity = 0.25 M
Explanation:
Answer:
Paraffin oil is used for determination of boiling point and melting point for the following reasons: It has a very high boiling point and so it can be used to maintain high temperatures in the boiling and melting point apparatus without loss of the substance.
16.94/18=.9411111
sig figs: 0.9411 mole of water
Answer:
