Answer: mass = 19 grams

Explanation: Density is directly proportional to mass and indirectly proportional to the volume. So, the density formula is:

density=\frac{mass}{volume}

density and volume are given and the question asks to calculate the mass. So, the formula could be rearranged as:

mass = density x volume

Given density is \frac{5.2g}{cm^3} and the volume is 3.7cm^3 .

Let's plug in the values in the formula to calculate the mass:

mass = \frac{5.2g}{cm^3}*3.7cm^3

mass = 19.24 grams

Both the density and volume have two sig figs, so if the answer is round off to correct number of sig figs then the mass will be 19 grams.

Calculate the number of ATPs generated by the complete metabolic oxidation of tripalmitin (tripalmitoylglycerol). Hydrolysis of
trapecia [35]

Answer:

Explanation:

412 ATP's will be generated from the complete metabolic oxidation of tripalmitin (tripalmitoylglycerol)

130 ATP from the oxidation of palmitate

22 ATP from the oxidation of glycerol

Altogether 130 + 22 = 412 ATP will be produced.

Here in case of tripalmitin (tripalmitoylglycerol), we have 51 carbons.

When 51 carbons can produce 412 ATPs

Then 1 carbon will produce how many ATPs = 412 ATPs/ 51 carbon= 8.1 ATPs.

This shows that ATP yield per carbon often oxidized will be 8.1 ATPs

Now we will see the ATP yield in the case of glucose.

Glucose is made up of 6 carbon and complete oxidation of glucose will produce 38 ATPs

When 6 carbons can yield 38 ATPs

Then 1 carbon can yield how many ATPs= 38 ATPs/ 6 carbons= 6.33 ATPs.

So, ATP yield per carbon in case of glucose will be 6.33 ATPs

How many atoms are in 4 moles of oxygen?
Paha777 [63]

Answer:

There are 6.022 × 10 23 O atoms in a mole of O atoms. There are 6.022 × 10 23 O 2 molecules in a mole of . Since you have 2 oxygen atoms in one molecule, there are 2 × 6.022 × 10 23 O atoms in a mole of . A 'mole' is not short for a 'molecule

Explain how Bohr's model built on the ideas of Einstein and Planck.
AlekseyPX

Explanation:

Bohr built on Nicholson's idea by adopting the requirement that the angular momentum can have only certain discrete values related to Planck's constant. However Bohr's atom has many orbits for the electrons.
