Answer:
There are 6.024 grams of sodium hydroxide in the solution.
Explanation:
Moles of sodium hydroxide = n
Volume of sodium hydroxide solution = 251.0 mL = 0.251 L
Molarity of the sodium hydroxide = 0.600 M
Mass of 0.1506 moles of NaOH :
There are 6.024 grams of sodium hydroxide in the solution.
Answer:
B. 88%
Explanation:
percent yield is the actual yield divided by the theoretical (predicted) yield, then multiplied by 100 to get a percentage.
110/125 = 0.88
0.88 x 100 = 88%
Answer:
29.0 g
Explanation:
We know that we will need a chemical equation with masses and molar masses, so let’s start by gathering all the information in one place.
: 63.55 46.01
Cu + 4HNO₃ ⟶ Cu(NO₃)₂ + 2NO₂ + 2H₂O
Mass/g: 20.0
1. Use the molar mass of Cu to calculate the moles of Cu.
2. Use the molar ratio of NO₂:Cu to calculate the moles of NO₂.
3. Use the molar mass of NO₂ to calculate the mass of NO2.

Explanation:
11/5 represents the mass number and the number of protons that boron has. 11 means that the total mass number, or the combined number of protons and neutrons is 11, while the 5 represents the number of protons. This means that the isotope must have 11-5=6 neutrons. Hope this helps!
Answer: C) When a force is applied to the crystal, the strong electrostatic interactions cause similar ions to repel and shatter the crystal lattice.
