What is the molarity of 62grams of ammonium in 5liters of water?
Viefleur [7K]

Answer:

Explanation:

First we need to find how many moles of ammonium weigh 62 grams.

Molar mass of NH4 = (14.0)+(4*1.0) grams

or 18.0 grams/mole

62 (g)/18(g/mole) = 3.444... moles of NH4

If it is dissolved in 5 litres of water, the concentration will be 3.444moles/5L

or 0.6888 M.

Forces and Motion:Question 1
defon

Answer:

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.
