Answer:
Explanation:
The time when they meet is t in hours
The general formula for both cars is d = r*t
t is unknown
r1 = 55 mph
r2 = 60 mph
60 mph * t + 55 mph*t = 100 miles
t * (60 mph + 55 mph) = 100 miles
t * 115 = 100 miles
t = 100 miles / 115 mph
t = 0.8696 hours
1 hour has 60 minutes
0.8696 hour = x
x = 0.8696 hours * 60
x = 52 minutes and 10 seconds
They will meet at 2:52:10

Answer: 306 grams are there in 2.50 moles of potassium chlorate
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the number of moles, we use the equation:
given mass of potassium chlorate = ?
Molar mass of potassium chlorate = 122.55 g/mol
Putting in the values we get:
306 grams are there in 2.50 moles of potassium chlorate
