Answer: The speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>
Explanation:
Given, The speed of a race car = 99 miles/ hour
To convert the speed into kilometers per hour and kilometers per minute
Since 1 mile = 1.61 kilometers
So, Speed of car = (99 ) x (1.61 )
= 159.39 kilometers per hour.
Also, 1 hour = 60 minutes
Then, Speed of car = (159.39) ÷60
= 2.6565≈2.65 kilometer per minute.
Hence, the speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>
Answer:
The molecular formula is C2H2Br4
Explanation:
Molar Mass of CHBr2 = 12 + 1 + (2x80) = 12 + 1 + 160 = 173
The molecular formula = n x empirical formula
Molar Mass of the compound = 345.6
Empirical formula = CHBr2
n(CHBr2) = 345.6
n x 173 = 345.6
n = 345.6/173 = 2
Therefore the molecular formula is n(CHBr2) = 2(CHBr2) = C2H2Br4
