Acar dives a constant speed of 65mph how far it traveled in 4 hours

The car traveled 260 miles in 4 hours.

Explanation:

Speed of the car = S = 65 mile/hr

Duration of time when the car was at speed S = T = 4 hours

Distance covered by car in T time = D

The car traveled 260 miles in 4 hours.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
