What volume of DI water, in mL, must you use to dissolve 30.0 g of NaOH in order to make a 1.25 M solution? mL (round to whole n
jeka57 [31]

Answer:

600mL

Explanation:

Molarity of a solution (M) = number of moles (n) ÷ volume (V)

number of moles = mass/molar mass

Molar mass of NaOH = 23 + 16 + 1

= 40g/mol

mole = 30/40

n of NaOH = 0.75mol

Using Molarity = n/V

V = number of moles ÷ molarity

V = 0.75 ÷ 1.25

V = 0.6L

In milliliters (mL), the volume of NaOH will be 0.6 × 1000

= 600mL

Corn plants may be tall (TT or Tt) or short (tt). The breeding of two parent corn plants results in offspring that are all tall.
zubka84 [21]

Answer:

0%

Explanation:

  • The probability that both of the parents are homozygous recessive is zero.
  • In our case, The gene for tallness is dominant over the gene for dwarfism
  • Therefore; TT is homozygous dominant while tt is homozygous recessive and Tt is heterozygous.
  • Heterozygous genotype (Tt) will exhibit a tall phenotype.
  • When two parents are crossed and all the offsprings are tall then the possible genotype of the parents is either;
  1. Homozygous dominant for both parents or  

       TT x TT

    2. One parent is homozygous dominant and the other is homozygous recessive.

        TT x Tt

  • Therefore, the probability of having both parents as homozygous recessive when all the offspring are tall is Zero.
