Answer:
33.33 h
Explanation:
You know that
1 h = 60 min
If you divide both sides by 60 min, you get the conversion factor: 1 h/60 min = 1.
If you divide both sides by 1 h, you get the conversion factor: 1 = 60 min/1 h.
Both are conversion factors because they both equal one and multiplying a measurement by one does not change its value.
You choose the conversion factor that gives you the correct dimensions for your answer. It must have the correct dimensions on top (in the numerator),
Thus, to convert 2000 min to hours, you use the conversion factor with “h” on the top.
Answer : The mass of ethylene glycol is, 437.34 grams
Solution : Given,
Volume of ethylene glycol = 394 ml
Density of ethylene glycol = 1.11 g/ml (Standard value)
Formula used :
Now put all the given values in this formula, we get the mass of ethylene glycol.
Therefore, the mass of ethylene glycol is, 437.34 grams
