Answer:

4 mL

Explanation:

Data Given:

Density (d) = 4.8 g/mL

Mass of the substance (m) = 19.2 g

Volume of the sample (V) = ?

Solution:

Formula will be used

d = m/V

As we have to find volume so rearrange the above equation

V = m/d . . . . . . . . . . . (1)

Put values in above equation 1

V = 19.2 g / 4.8 g/mL

V = 4 mL

So,

volume of sample = 4 mL

Please HELP!

abruzzese [7]

This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.

1st possibility:

B B

B BB BB

b Bb Bb

Brown eyes: 4 out of 4 or 100%

Blue eyes: 0 out of 4 or 0%.

2nd possibility:

B b

B BB Bb

b Bb bb

Brown eyes: 3 out of 4 or 75%

Blue eyes: 1 out of 4 or 25%.

3rd possibility:

b b

B Bb Bb

b bb bb

Brown eyes: 2 out of 4 or 50%

Blue eyes: 2 out of 4 or 50%.

As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is Bb or BB, then BROWN in this case will come out. The only time BLUE eyes will come out is if has two recessives in its genotype or bb.

By weight atmospheric air is approximately 23.15% oxygen and 76.85% nitrogen. What is the partial pressure of oxygen in the air

inna [77]

Answer:

Partial pressure of oxygen = 23.38 kpa (Approx)

Explanation:

Given:

Amount of oxygen = 23.15%

Amount of nitrogen = 76.85%

Pressure (missing) = 101 kpa

Find:

Partial pressure of oxygen

Computation:

Partial pressure of oxygen = [Amount of oxygen x Pressure]/100

Partial pressure of oxygen = [23.15% x 101]/100

Partial pressure of oxygen = 23.38 kpa (Approx)

What mass of propane (c3h8(g)) must be burned to supply 2775 kj of heat? the standard enthalpy of combustion of propane at 298 k

Shalnov [3]

Answer is: 55.125 grams of propane must be burned.
Balanced chemical reaction: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
Make proportion: 1 mol(C₃H₈) : 2220 kJ = n(C₃H₈) : 2775kJ.
n(C₃H₈) = 2775 kJ·mol ÷ 2220 kJ.
n(C₃H₈) = 1.25 mol.
m(C₃H₈) = n(C₃H₈) · M(C₃H₈).
m(C₃H₈) = 1.25 mol · 44.1 g/mol.
m(C₃H₈) = 55.125 g.
n - amount of substance.
