Answer:
Percent Composition
1. Find the molar mass of all the elements in the compound in grams per mole.
2. Find the molecular mass of the entire compound.
3. Divide the component's molar mass by the entire molecular mass.
4. You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

Also with protons and electrons they equal the same atomic number
We will not be able to tell the genotype of the purple parent as it can either be a homo_zygous dominant or hetero_zygous. Without the complete genotype of the offspring, we would not be able to tell.
Answer:
It's just asking you to rearrange to equations to get what you want, so no numbers involved it's just teaching you the basics.
Explanation:
Answer:
The partial pressure of hydrogen gas at equilibrium is 1.26 atm
Explanation:
Let's use the molar fraction to solve this:
Molar fraction = Moles of gas / Total moles
Molar fraction = Gas pressure / Total pressure
Without equilibrium, we can think that the total system pressure is the sum of the partial pressures of each gas.
1 atm N₂ + 2 atm H₂ = 3 atm
Molar fraction for H₂ = 2 atm / 3atm → 0.66
Let's replace the molar fraction in equilibrium
Gas pressure / 1.9 atm = 0.66
Gas pressure = 1.26atm
