Tt
I believe this is the answer because it is completely recessive.
A combination of TT or Tt would result in a dominant phenotype.

How many molecules does 88 grams CO2 contain? A) 1.2 X 1024 B) 1.8 X 1024 C) 3.0 X 1023 D) 6.0 X 1023
mylen [45]

Hey there!:

Molar mass CO2 = 44.01 g/mol

44.01 g CO2 ------------------- 6.02*10²² molecules CO2

88 g CO2 ------------------------ y

y = 88 * ( 6.02*10²² ) / 44.01

y = 5.29*10²⁵ / 44.01

y = 1.2 * 10²⁴ molecules of CO2

Answer A


Hope that helps!

The sulfur content of an ore is determined gravimetrically by reacting the ore with concentrated nitric acid and potassium chlor
katen-ka-za [31]

Answer:

13.92 %

Explanation:

Mass of BaSO_4 = 12.5221 g

Molar mass of BaSO_4 = 233.43 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{12.5221\ g}{233.43\ g/mol}

Moles of BaSO_4 = 0.0536 moles

According to the given reaction,

Ba^{2+}_{(aq)}+SO_4^{2-}_{(aq)}\rightarrow BaSO_4_{(s)}

1 mole of BaSO_4 is formed from 1 mole of SO_4^{2-}

Thus,

0.0536 moles of BaSO_4 is formed from 0.0536 moles of SO_4^{2-}

Moles of SO_4^{2-} = 0.0536 moles

Moles of sulfur in 1 mole SO_4^{2-} = 1 mole

Moles of sulfur in 0.0536 mole SO_4^{2-} = 0.0536 mole

Molar mass of sulfur = 32.065 g/mol

Mass = Moles * Molar mass = 0.0536 * 32.065 g = 1.7187 g

Mass of ore = 12.3430 g

Mass % = \frac{Mass\ of\ Sulfur}{Mass_{ore}}\times 100 = \frac{1.7187}{12.3430}\times 100 = 13.92 %
