Molarity= (number of moles of that substance) / (Volume of solution in litres)
7= (number of moles of HCl) / 0.05
Thus,
Number of moles of HCl = 7 x 0.05 = 0.35
The number of moles of HCl will remain unchanged.
Now, for new solution,
0.35= 0.35 / (New volume of solution in litres)
Thus,
New volume = 1 litre
Thus, amount of water added = 1- 0.05 litre = 5.0 M
The engine displacement in cubic nanometer (nm³) is 8.785×10²⁴ nm³
<h3>Data obtained from the question </h3>
- Displacement in in³ = 536 in³
- Displacement in nm³ =?
<h3>Conversion scale </h3>
1 in³ = 1.639×10²² nm³
With the above convesion scale we can obtain the displacement in nm³
<h3>How to determine the displacement in nm³</h3>
1 in³ = 1.639×10²² nm³
Therefore,
536 in³ = 536 × 1.639×10²²
536 in³ = 8.785×10²⁴ nm³
Thus, the displacement in nm³ is 8.785×10²⁴ nm³

Answer:
2.938 mol Pb(NO₃)₄
Explanation:
Step 1: Given data
- Moles of NH₄NO₃ to be produced: 11.75 mol
Step 2: Write the balanced equation
4 (NH₄)₃PO₄ + 3 Pb(NO₃)₄ = Pb₃(PO₄)₄ + 12 NH₄NO₃
Step 3: Calculate the number of moles of Pb(NO₃)₄required to produce 11.75 moles of NH₄NO₃
The molar ratio of Pb(NO₃)₄ to NH₄NO₃ is 3:12.
11.75 mol NH₄NO₃ × (3 mol Pb(NO₃)₄/12 mol NH₄NO₃) = 2.938 mol Pb(NO₃)₄

Answer:18 g
Explanation:
The molar mass of dextrose is obtained as shown. Then the formula for number of moles is applied as shown in the image. Number of moles= mass/molar mass= concentration × volume. The volume is measured in dm3 hence the denominator of 1000. By making mass of solute the subject of the formula, we obtain the mass of dextrose requited to prepare the desired concentration of solution in the desired volume.
