.722 mols of H2 because hydrogen gas molar mass is 2.02 so divide 1.46/2.02
Answer:
79 minutes
Step-by-step explanation:
A plane is travelling at 180 meters per seconds
Convert to km/hr
180× 18/5
= 648 km/hr
Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is
= 1/648 × 800
= 1 hour 19 minutes
Conver the time to full minutes
60 minutes = 1 hour
= 60+19
= 79 minutes
Hence the minutes required for the plane to travel 800km is 79 minutes
Is 4:30 because ,12:45 take away 8:15= 4 :30 and 8 to 12 they are 4 and 45 take way 15 is 30
