KHP is an acronym which stands for potassium hydrogen phthalate. It is an acidic salt which is white crystalline powder at room temperature. When in solution it is colorless. It has a chemical formula of C8H5KO4. Molar mass of a compound is the sum of the masses of all the atoms involved in the structure of the compound. So, we need the atomic masses of the elements involved. We do as follows
C = 12.01 g/mol x 8 = 96.02 g/mol
H = 1.01 g/mol x 5 = 5.05 g/mol
K = 39.10 g/mol x 1 = 39.10 g/mol
O = 16 g/mol x 4 = 64 g/mol
Adding, we will have 204.17 g/mol. This would be the molar mass of KHP.
Answer:
Creativity
Skepticism
Reasoning
Explanation:
Scientists must see a creative way to solve problems in the world. Scientists must also be skeptic about what is said, because if they were not, no one would disagree and the problems would never be solved. Reasoning is a must, as reasoning is involved in the scientific process and writing conclusions to their studies.
Hope this help!
Answer:
8.3 g
Explanation:
Step 1: Write the balanced equation
H₃PO₄ + 3 NH₃ ⇒ (NH₄)₃PO₄
Step 2: Calculate the moles corresponding to 5.5 g of H₃PO₄
The molar mass of H₃PO₄ is 97.99 g/mol.
5.5 g × 1 mol/97.99 g = 0.056 mol
Step 3: Calculate the moles of (NH₄)₃PO₄ produced
The molar ratio of H₃PO₄ to (NH₄)₃PO₄is 1:1. The moles of (NH₄)₃PO₄ produced are 1/1 × 0.056 mol = 0.056 mol.
Step 4: Calculate the mass corresponding to 0.056 moles of (NH₄)₃PO₄
The molar mass of (NH₄)₃PO₄ is 149.09 g/mol.
0.056 mol × 149.09 g/mol = 8.3 g
A frequency of 60 MHz is close to the lower end of the old VHF-TV band.
c = f λ ...... where c is the speed of light, f is the frequency and λ is the wavelength
λ = c / f = 3.00x10^8 m/s / 6.0x10^7 1/s
λ = 5.0 m
