Sally's brother is color-blinded. her husband is normal. what is the chance for her son to be color-blinded?
1 answer:
The inheritance of colorblindness gene is X linked. Sally is a female, she'll have two copies of X chromosomes. Since she is not colorblind indicates that she is a carrier of the gene, the presence of at least one functional gene on either of the X chromosome in Sally prevented colorblindness in her. The chances that her husband will have a colorblind child is 25% (1:3) and 50% for the colorblind son (1:1),based on the solved punnett square in the image, where X' denotes the colorblindness gene.

Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n =
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
