Convert .0150 km to meters and express the correct significant figures
weeeeeb [17]
<h3>Answer:</h3>

15.0 meters

<h3>Explanation:</h3>
  • Kilometers are units used to measure length.
  • Length is also measured using other units which include meters, centimeters, decimeter, millimeter, etc
  • To convert one unit to another we use conversion factors.

In this case to know inter-conversion between units of measuring length, we consider the following;

Kilometer(km)

10

Hectometer(Hm)

10

Decameter(dam)

10

Meter (M)

10

Decimeter (dm)

10

Centimeter (cm)

10

Millimeter (mm)

Therefore, to convert km to meter we use the conversion factor (10×10×10) 1000 m/km.

Thus;

0.0150 km is equivalent to;

= 0.0150 km × 1000 m/Km

= 15.0 meters

Thus, 0.0150 km is equivalent to 15.0 meters.

3. Given 20g of Barium Hydroxide, how many grams of
anastassius [24]

The number of grams of ammonium nitrate (NH₄NO₃) it would take for all the barium hydroxide to react is 18.7g

First, we will write the balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

Ba(OH)₂ + 2NH₄NO₃ → 2NH₄OH + Ba(NO₃)₂

This means, 1 mole of barium hydroxide is required to react with 2 moles of ammonium nitrate

Now, we will calculate the number of moles of barium hydroxide present.

Mass of barium hydroxide (Ba(OH)₂) = 20 g

Using the formula

Number\ of\ moles = \frac{Mass}{Molar\ mass}

Molar mass of Ba(OH)₂ = 171.34 g/mol

∴ Number of moles of Ba(OH)₂ present =\frac{20}{171.34}

Number of moles of Ba(OH)₂ present = 0.116727 mole

Now,

Since 1 mole of barium hydroxide is required to react with 2 moles of ammonium nitrate

Then,

0.116727 mole of barium hydroxide will react with 2 × 0.116727 mole of ammonium nitrate

2 × 0.116727 = 0.233454 mole

∴ Number of moles of NH₄NO₃ required is 0.233454 mole

Now, for the mass of ammonium nitrate (NH₄NO₃) required

From the formula

Mass = Number of moles × Molar mass

Molar mass of NH₄NO₃ = 80.043 g/mol

∴ Mass of NH₄NO₃ required = 0.233454 × 80.043

Mass of NH₄NO₃ required = 18.68636 g

Mass of NH₄NO₃ required ≅ 18.7g

Hence, the number of grams of ammonium nitrate (NH₄NO₃) it would take for all the barium hydroxide to react is 18.7g
