60 miles per hour in meters per second

26.8224 m/s

Explanation:

We know that 1 mile = 1.609344 kilometers

So 60 miles * 1.609344 = 96.56064 Kilometers

We also know that 1km = 1000m

Therefore, 96.56064 x 1000= 96,560.64 M/h

And 1 hour = 60 * 60 = 3600 s

Therefore 96,560.64 (m/h) /3600 s =26.8224 m/s

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
