A distance-time graph indicates that an object travels 2 m in 2 s and then travels another 30 m during the next 40 s.

Chemistry
1 answer:
Doss [256]3 years ago
5 0

Answer:

\boxed{\text{0.76m/s}}

Explanation:

\text{Average speed} = \dfrac{\text{total distance}}{\text{total time}}

Total distance = 2 m + 30 m = 32 m

      Total time = 2 s  + 40 s   = 42 s

\text{Average speed} = \dfrac{\text{32 m}}{\text{42 s}} = \textbf{0.76 m/s}\\\text{The average speed of the object is $\boxed{\textbf{0.76m/s}}$}

A solution is prepared by dissolving 15.0 g of NH3 in 250.0 g of water. The density of the resulting solution is 0.974 g/mL. The
iVinArrow [24]

Answer:

[NH₃]  → 3.24 M  

Explanation:

Our solute: Ammonia

Our solvent: Water

Solution's mass = Mass of solute + Mass of solvent

Solution's mass = 15 g + 250 g = 265g

We use density to determine, the volume.

D = mass /volume → Volume = m / D →  265 g /0.974 g/mL = 272.07 mL.

We convert the mL to L → 272.07 mL . 1L /1000mL = 0.27207 L

To determine molarity we need the moles of solute in 1 L of solution.

Moles of solute are: 15g / 17g/mol = 0.882 moles

[NH₃] = 0.882mol /0.27207 L → 3.24 M
